Html5 and javascript host.
  * sets mediump by default for float in fragment shader (explicit definition of precision is required by webgl)
  * Changed libfreetype cmake file to generate a buildable source ( currently defined symbols multiple times which gcc is happy with but not clang)
  * builds webuntz instead of untz (interface compatible) may need its own cmake file/folder to clean it up
  * skips glew but does so differently to blackberry. I can change later if needed
fix paths in cmake files. Not sure how this was working for zipline,
Build now works and creates the template.
Update readme with new build instructions
updated host-template readme with more instructions
