		[p]
		Registers a script-based addon.
		[/p]
		[p]
		The registration process allows to "show" the addon in the script-addon manager
		dialog and provides a standard way for the user to manage and uninstall the addons.
		You simply register your addon BEFORE attempting to install it.
		[/p]
		[p]
		A script-based addon is a set of scripts, icons, translations and possibly
		other data files that add functionality to the KVIrc program.
		The script-based addons are often simply called "scripts" and
		we will adhere to that naming in certain parts of the documentation too.
		[/p]
		[p]
		Each script-based addon (a set of scripts) is identified by an UNIQUE
		<id>. Two addons with the same <id> can't co-exist in the same
		KVIrc installation (so be sure to choose a token characteristic enough
		to avoid collisions with others). The <id> itself is used only for
		identification purposes and the user will almost always see the <visible_name>
		instead, which can contain the [fnc]$tr[/fnc] function that will handle
		the translation for it.
		[/p]
		[p]
		Each addon has also a <version> which is a string in the form x.y.z
		where x, y and z are numbers (yes.. that's the standard major-minor-patch level
		version numbering scheme). A <version> of 2.4.23 is greater than 2.4.3
		even if 2.4.3 comes after when compared as a string.
		When an addon with a greater or equal version is installed over
		an addon with a lower version, the lower one gets uninstalled first.
		Installing a lower version over a greater one is not possible, unless
		the lower versioned one is uninstalled first.
		[/p]
		[p]
		<description> is another, possibly translated, string that will
		be presented to the user in the addon management dialog.
		[/p]
		[p]
		<minkvircversion> is the minimum KVIrc version required for the
		addon to run. If the version of the running KVIrc executable
		is lower than the requested one then the command will abort with an error.
		If you want to completly ignore the KVIrc versioning (don't do it),
		use "0.0.0" here. If you need fine tuning on cvs features you may add also
		the sources date tag at the end of the required version string (e.g 3.2.1.20060303).
		[/p]
		[p]
		<iconid> is the [doc:image_id]image identifier[/doc] of the icon
		that will be displayed in the addon management dialog.
		If not specified, a default icon will be used.
		[/p]
		[p]
		The <uninstall_callback> is a snippet of code that should
		wipe out the addon from the system. It is ALWAYS a good practice
		to write a complete uninstallation procedure (think that YOU like
		to be able to completly uninstall a program that you don't use anymore).
		The <uninstall_callback> will be called by KVIrc when the addon
		uninstallation is requested, either explicitly by using the GUI or the
		command [cmd]addon.uninstall[/cmd], or implicitly by installing
		a newer version of the addon (upgrading).
		[/p]
		[p]
		If the user security rules don't allow your addon to be installed
		or a higher version of a addon with the same name already exists
		the command will fail with an error (aborting your whole intallation addon).
		If you don't want to fail with an error but handle it gracefully instead
		then you should use [fnc]$addon.exists()[/fnc] to check if a
		addon with the same name and a greater version already exists.
		You can't gracefully handle security error conditions: your installation
		will be always aborted with an error in this case.
		[/p]
		[p]
		The addon can also have a configuration callback settable with [cmd]addon.setconfigurecallback[/cmd]
		and a help callback settable with [cmd]addon.sethelpcallback[/cmd]. The first
		will usually display a configuration dialog, the second will display
		some sort of addon's documentation, usually in the help browser.
		[/p]
		[p]
		The registration process uninstalls any previous addon version
		by executing its uninstall callback routine. This is another reason for that
		you should call addon.register BEFORE you attempt to install your addon.
		Failing to do that may cause your old uninstalled to wipe out your newly
		installed files or code.
