Dwoo - a PHP Template Engine

Changelog

+ Full template cache support
+ DwooTemplateString class to load templates from a string
+ Dwoo::VERSION constant
+ {dump} plugin to print out variables
+ Unit tests (with PHPUnit) covering 73% of the codebase right now, which should help reducing regression bugs in the next versions.
+ Started commenting (with phpdocs) properly all the classes, should be complete for 0.4.0
* {capture} is now compilable and has a new boolean flag to append output into the target variable instead of overwriting
* {foreach} supports direct input (instead of only variables), allowing constructs like {foreach array(a,b,c) val}{$val}{/foreach} for example that would output abc.
* pre/postProcessing functions in block plugins now receive an array of named parameters instead of numbered
* Major refactoring of DwooTemplateFile and DwooCompiler
* Cleaned up members visibility in Dwoo/DwooCompiler
* Fixes in the compiler parsing and general variables handling
* Multiple bugfixes here and there thanks to the unit tests
* Optimized {foreach} a lot
