v1.7: added `--no-source` option, foxpro, SQL support.

* Added `--no-source` option. By default JLP copies the original source code
  into the output directory. THis option disables that behavior.
* Added basic error handling after parsing input files: input files that do not
  parse correctly are ignored. Beforehand they were causing null pointer
  exceptions in the second parse phase of the processor.
* Made the top-level support directories hidden in the output root (ie. `/.css`
  instead of `/css`.
* Added configuration to handle Visual FoxPro files (no syntax highlighter
  available) and SQL files.
* Expanded the list of binary file types. Binary and unknown file types are not
  parsed.
