Allow proportional scaling of thumbnals and images
It was impossible to set with or height to 0 as it then always default settings were used.
This is now possible. Default values are now only used if other than digits are in those parameters.
thumbnail(img, 400, 0, 'r') now gives you as expected an image with height scaled proportional instead of deefualt height.
add an extra path for composer
define this before call to parent
Hopefully a fix for Issue 1245 and support for absolute paths on Windows sytems
some changes to composer resources to fix theme loading errors
set path correctly for composer root
add composer path set into constructor
add paths into constructor and out of initialise block
leave theme seting to app after config load
force the setTwigPath method to use the defined themepath
add an initializeConfig event to allow hooks to config load
reinstated accidentally deleted block
Removing the clusterfuck that is Browscap.
