Suggested function for WCX interface

[Alextp]

Hello Christian,
Here is suggestion for next TC version, for plugins installing:
Add to WCX interface function GetPackerExtensions.
If it returns string: e.g. "iso bin nrg"(convert to lowercase),
TC should add plugin as this:

[PackerPlugins]
iso=nnn,filename.wcx
bin=nnn,filename.wcx
nrg=nnn,filename.wcx

where nnn:= IntToStrDef(GetPackerCaps, '0')

And if it returns: "nnn1,iso nnn2,bin nrg" TC should
register using numbers nnn1,nnn2 (default is '0').

This is for easy installing plugins that have several extensions
(e.g. iso.wcx, msi.wcx, multiarc.wcx)

In my TC_Plugman I'll also use this function.
Regards,
