Remove bundled fsharp-mode

Don't include fsharp-mode your .emacs.d; it's better pulled in from a package
repository if necessary.
Remove bundled go-mode
Remove bundled android.el
Remove bundled csharp-mode
Remove bundled powershell-mode
Remove bundled groovy-mode
Remove bundled folding.el

Actually wasn't using this at all
Remove bundled vala-mode
Remove bundled visual-basic-mode
Remove bundled eperiodic.el
Remove bundled php-mode
Remove bundled erlang-mode
Remove bundled sudoku.el
Remove bundled eimp.el

I honestly cannot remember what I was even using this for...
Remove bundled yaml-mode
Remove bundled git.el and git-blame.el
Remove bundled color-theme
Remove bundled alt-font-menu.el

Don't know why I should need this offhand.
Remove bundled markdown-mode
