* Add support for creating torrents with a source flag
* Add the source flag functionality for Mac OSX
* Source flag should be a part of the info dictionary
* Address review comments
* Rename "sourceFlag" to "source" since "Flag" is usually reserved for booleans.
* Free the "source" pointer in tr_metainfoFree.
* Add information about transmission-create argument to its manpage.
* Replace all occurences of "sourceFlag" with "source" and use "Source tag" in UI
* Settle on just "Source" in UI
* The last usage of "flag" hopefully bites the dust! ;-)
* Add a missing free for the source in tr_metainfoFree
* Add a "source" field to the torrent-get RPC method
* uncrustify
* Test for torrents having different infohashes due to different source flags.
This is the whole point of this feature, so it makes sense to test it.
* case is important
* try to incorporate the macosx xml changes
Split FileTree.{h,cc} and FilterBar.{h,cc} files so that each class
is in its own file.
This breaks translations (some classes got renamed => context changed),
to be fixed by next commit (along with Tx sync).
