remove auto-generated files

[wchristian]

As discussed in IRC, the *.inc files should not be in the repo in the first places. This commit removes them, puts them in .gitignore and ensures the files are generated when MfPL is being run, thus making it easy to cut releases with the proper files.

This obsoletes PR #12.

Thanks for the fix. I'll make the pull once I figure out how to resolve the conflicts with the current git head.

I rebased it onto master, only needed the newline fixes applied for git to be able to make sense of it.

Note in general: Don't use warn for debug output. Output on stdout, warnings and errors on stderr.

[devel-chm]

Thanks. I'm working on making generate-XS.pl generate the needed files starting with the priority list used by prima, microidium, app-shadertoy, and pdl. See the branch chm_generate-XS_work for details including a directory pogl_implemented with lists of the routines implemented in OpenGL and their variations with suffixes.

chm_generate-XS_work looks like you merged after a rebase, which is superfluous and messes up the structure.

You'd wanna reset the branch to 1cab718 and do a force push instead.
