Fixed dozens of issues in the deps parser.
Fixed dozens of issues in the deps parser.

Major one includes:

- No more VAR_NAME token. Everything is treated as a WORD now. This
  fixes all sorts of issues with upper camel cased words and other
  capitalized stuff.

- next_line no longer stops on empty line if it already has contents.
  This fixes the issue where trailing slashes at the end of long
  variable definitions would slurp in the next line causing all sorts
  of trouble.

- keywords are now actively ignored at the begining of a line. Cuts
  down on error messages.

- unknown vars will now simply be ignored during expansion.

- Better sub_make parsing for various edge cases.

- Petter output and control over the output.
