compass 6.x-1.0-beta2

This beta fixes many serious bugs from the earlier beta. This now requires Compass v0.10.0.pre5 and PHP 5.

use --boring argument to turn off color output.
fix cron jobs. log all cron jobs.
wrap compass output in

 tags for better display.
overcome fgets() block by using stream_set_blocking() and stream_get_contents().
  stderr buffer was filling up before stdout was giving its EOF, which caused the compass to hang and stylesheets were not compiling reliably.
  php5 is now required for use of stream_get_contents().
default path to compass was "/usr/bin/convert" in _compass_exec().
