ComposerTask: 	 Fixed issue with incorrect command line after subsequent calls in the same build file
Merge pull request #205 from JostBaron/master

Added Smarty 3 compatibility
Added first version of a Sass-Task based on PHPSass (http://www.phpsass.com). Still quite crude.
Made SassTask run on every invocation, not only if the input template has changed.
Added two property 'baseDirectory', which sets the directory in which files included by @import clauses are searched, and 'style', which determines the output style.
