New feature: add-file functionality to Projucer

[tesseiko]

Added new subcommands to Projucer command line.

Projucer --clear-maingroup jucerfile.jucer Projucer --add-file jucerfile.jucer path/to/file/or/directory/to/add/project

Here is the patch, in case anybody wants to patch this feature to a previous version. Tested in 6.1.6.
