Remove meta/generated files in the project and ignore them.

[CoatedMoose]

Pretty much everything in the nbproject (except for _____???) are generated files. These should be removed and .gitignore'd as appropriate. This will prevent the emergence of future merge conflicts on these files, which we don't actually need/want to deal with (since they are generated anyway).

Cleaned up as much as possible. The remaining files depict important settings such as the chip being used, the files in the project, etc.
