Basic react server done.
Added special html atributes and loverCase camel-cased.

Added functionality for `"className"`(`"class"`) and `"htmlFor"`(`"for"`)

LowerCase all atributes to create valid html.
Test with prebuild html
rebase, update tests, update to simplified ComponentFactory
Merge branch 'master' into react_server

Conflicts:
