[APSTUD-8188] Created a mock EDTFTPj-pro library

Stuck this into com.aptana.libraries as a .jar file. Also added mock license files. Suggestion is we just copy over the real files on the build server. Users who wish to buy the real version of the library can just drop it over the top.

Testing: No build errors, product launches as expected. Using the FTP libraries results in...badness. We may wish to consider throwing alerts or exceptions.
