Merge pull request #172 from sprowell/master

Bit string updates.
Made changes to support unit testing. The first new test is for the bitstring.eli file.  Added a new method to Processor to turn the ParseResult into a list of basic atoms.
Removed Bitstring.eli from Boot.eli, which needs to be added back for the unit test to work.  Fixed ProcessorTest to work with the ERepl changes.
The files_inc.eli file is now being pointed to a more standard location, but there is some error compiling native handlers with this approach.
