Fix default value in WJEDouble get.
Added callbacks that can be used when writing a document to allow filtering or changing "pretty" values
- selector fix: use WJEChild instead of WJEGet where appropriate
- added some documentation about selectors/WJEGet/WJEChild
fix compiler warnings
 still requires "-Wno-char-subscripts" when compiled with "-Wall"
Style changes
- Added tests for returning default values when using WJE_GET
- Updated 'defaults' test to to handle existing property with null value
- Minor style cleanup
fix caps typo: WJOpenFILEDocument
introduce WJEWriteFILE()

To be able to call the WJEDump() function from gdb and for the sake
of readable function names, don't use a macro to do writing to a FILE*
add documentation of WJEWriteFILE()
