[chuck] version 1.1.5.4 released + keywords

[Ge Wang]

Dear All,

chuck-1.1.5.4 is another incremental update with bug fixes
and one rather questionable new keyword:

     http://chuck.cs.princeton.edu/

we apologize for the lack of language references.  there is
now a somewhat definitive list of keywords:

     http://chuck.cs.princeton.edu/doc/program/keywords.html

this is mirrored from the wiki - feel free to post stuff here:

Please let us know if there are any issues.

1.1.5.4 - 2004.11.18
   - fixed clicks when using adc unit generator
     (thanks to paul botelho for testing)
   - added 'maybe' keyword
     maybe == 0 or 1, with 50% probability each

new examples:
   - maybe.ck : the maybe keyword - bad idea? maybe.
   - maybecli.ck : maybe click, maybe not

adc examples work better:
   - adc.ck
   - echo.ck
   - i-robot.ck

HappY ChucKing!

Best,
ChucK team
