Documentation Updates

Slight modification to README.md

Removed Clonezilla entry in pxelinux.cfg/default that was accidentally
entered in a previous commit

Deleted TODO.md since all entries are either open/closed issues in
GitHub (better tracking on GitHub than in a static text file) and made
mention of the issues page in README.md
