- started work on experimental sax based alternative parser:
 * this avoids loading the whole xml into memory which will avoid crashes/excessive memory use
 on large amf files
 * added specs, but is not functional for now : work in progress !

- minor cleanup in current parser & browserDemo
- added RoboIce-dual test file : this crashed the current parser, but will need to be loaded just
fine with new parser
- further work on sax based parser : not there yet, but pieces are starting to work
- very basic implementation of sax parser works:
 * code is awfyully dirty for now
 * added specs to check various specific parsing aspects
 * fixed one data file (constellation) : turns out the parser (correctly) showed an xml structure error : neat!
