Improvements for "List of Extensions" Output

[whimboo]

Originally filed as: https://bugzilla.mozilla.org/show_bug.cgi?id=629368

With the release of Stylish 1.1, users now have all Extensions, Themes, Plugins, Styles, & Scripts output and mixed together when selecting Copy/Insert (their) List of Extensions from the NTT submenu. That makes things a royal pain if, like me, the user has many (79 combined) of these items installed.

I have some suggestions for improving this output.

First Possibility:

Separate menu line items for Extensions, Themes, Plugins, Styles, & Scripts.

Second Possibility:

Segregate the output of the current submenu item by Extensions, Themes, Plugins, Styles, & Scripts

Example:

Extensions:
Extension 1
Extension 2

Themes:
Theme 1
Theme 2

Plugins:
Plugin 1
Plugin 2

Style:
Style 1
Style 2

Script:
Script 1
Script 2

Also Langpacks (which are listed on a separate "Languages" tab in about:addons, but that tab disappears if no other language is installed that the one hwich came built-in at install-time). Installed as {profile}/extensions/langpack-{language}[-country]@{application}.mozilla.org.xpi with em:type=8 in the outside Description tag in install.rdf.

The following method will give us a list of all installed types of add-ons:

It would be a good starting point for someone who wants to contribute some code.
