Fixed commit message feature after d.o D7 upgrade.
Re-added uglify to build task.

Uglification (beyond minification) can improve performance of the JavaScript parser/compiler at runtime, due to consecutive `var` statements, removal of duplicate variables, AST code logic optimizations, etc.

Uglification is only enabled for the default `grunt build` task, because it would needlessly slow down realtime development.

Lastly, we only care for uglification, not for minification.  Therefore, uglify is configured to beautify the code after performing optimizations.

Fixed JSON parse error.
