Integrate touch related development. (#90)

* * Add BuildActionIntention crap

* * Set Client and World projects to use MP compilation

* asd

* * Use the new BuildActionIntention to break and place blocks.

* * Reverse engineer the IArea system.

* * Copy break logic from survival into creative conditionally

* * Reverse IBuildInput and MouseHandler
* Replace the new relative paths in the client project with $(MC_ROOT) again

* * Reverse Multitouch, MouseDevice

* * Reverse a bunch of auxiliary classes for input.

* * Use CustomInputHolder instead of holding inputs manually.

* * Reverse a whole BUNCH of things!

* * Add feedback textures to the gitignore.

* * D-pad now renders! Also loads of other work.

* * More Stuff

* * Finish touch control bug fixing.

* * Finalize work.

* * One last thing..

* * Add a "cramped" mode to the options screen and start menu.

* * Oh, forgot to do something
