Added missing eclipse-required build files

Dear anyone who ever tried to build this project from the github repo
before this commit: I'm sorry
Fixed bad .gitignore formatting
Fixed eclipse .project's project name entry
Updated readme formatting, copyright
Added .gitattributes and fixed line endings
Added 4 new ad providers

Special thanks to Asher Delug, CEO of Airpush, for providing their
names. I don't know why it never occurred to me before that every ad
company would be *thrilled* to have me be picking up all of their
competitors.
Added dialog informing 4.1+ users of obsolesence
3.2 version bump
