Fixing the gitignore

that xbony2 broke yesterday...

there will be a rather large commit tomorrow, fixing pretty much every
bug we've had since I joined the team, the commit will require forge
1.7.10_10.3.2.1230 at least to run, just in case someone doesn't have
the latest forge.

some changes coming tomorrow:
hammer calls "rotate" in TileEntityTrackBase instead of handling the
logic on its own. EVERYTHING about tracks except for the TRACK_TYPE,
MUST now be handled via TileEntityTrackBase... this includes color...
Sloped tracks will place dummies properlly, and handle their rotation
properlly, this is made much easier by the new BlockSnapshot class and
the new PlaceEvent and MultiPlaceEvent stuff added in forge 1230. The
rendering for the new corkscrew models will be fixed, may or may not get
models for the other styles in tomorrow... but the models will be a low
priority thing, seeing moderate updates over the next few releases.
Tracks will place facing relative to the player, and will have smarter
placement mechanics to accomodate the dummies.
