small fixes
moved all the packagist dependencies to the appropriate core or plugins composer.json,

i can not move the remaining dependencies, since custom package definitions are not yet resolved recursively
- always build less when in development (type is allways set, so it would never build otherwise)
- always build both mobile and core
- always generate compressed version aswell as normal version
added Helper::compileStylesheet (inFile, outFile) function with support for compression
updated smarty Singleton to use newly defined PATH_SMARTY (by accident found out about SMARTY_DIR define, which is set by smarty itself :) )
Smarty is autoloaded
improved the upload js function
Merge branch 'development' of github.com:cnlpete/candyCMS-Core into development
added missing closing tag for tab-content
Merge pull request #13 from cnlpete/development

small fixes, proper dependencies
