Renamed rake task
Default Style for TinyMCE available tags
Merge pull request #134 from mukkoo/master

good!
use DIRECTORY_SEPARATOR constant
added DirHelper class
added plugin_path function that returns the path where wordless
plugin is installed
use plugin_path method instead of WP_CONTENT constant to get wordless
path
renamed to PathHelper
Merge branch 'master' of https://github.com/welaika/wordless
added phptydy files to gitignore
added theme_path to Wordless class
made process_file in less_preprocessor compliant with the parent implementation
probablya  bad solution, but avoid warnings
ported functional-php functions to Wordless as functional_helper
ported tests (they pass 99%, there are still some left TODO)
credits for functional-php functions go to Lars Strojny
