cross platform build automation

[marc-portier]

The current bash scripts for automated build are not really windows friendly.

Since js/cc brings a dependency to rhino anyway we might think about assuming that as a basis for automation of the build as well.

Other things to note:

• location of the ebnfdia-jq.js (not under src/**) is somewhat confusing
• actually the templating trick itself is a bit over the edge too: ebdf-jq.js is the only thing we really need (the *-cli is only there for rhino testing, and was historicaly the first to exist) >> looking at the jquery take it might be wiser to:
  • let js/cc generate ebnf-jq.js directly if possible, and
  • use qunit for tests rather then the current ebnf-cli.js
