Feature: Main menu item "Videos"

[wutschel]

As suggested in this forum post it is desirable to have a dedicated "Videos" main menu entry. Currently Videos are only accessible via the file mode access under the "Movies" main menu.

Idea:

• Have "Videos" main menu entry
• "Videos" toolbar direct access: "File mode", "Music Videos", "Recently Added"
• "Videos" toolbar "more menu": "Video Add-ons" and "Video Playlists"
• In "Movies" tools "more menu" the entry for "Music Videos" will be removed

Draft implementation has a few changes for consistency:

• Have "Videos" main menu entry
• "Videos" toolbar direct access: "Music Videos", "Recently Added Music Videos", "File mode", "Video Add-ons"
• "Videos" toolbar "more menu": "Video Playlists"
• In "Movies" toolbar's "more menu" the entry for "Music Videos" will be removed
• In "TV Show" toolbar's "more menu" an entry for "Video Playlists" will be added
