Also fixed uniforms that are missing

Went back to old rendering for simplicities sake. We can look at going
back later during the performance pass

Also created global uniformGroup
Broke up webGL to projection / renderTexture manager
I’m on to something here! Almost there..

Base texture replaced..

The `vertSize` is 5 , but the content is not `positionX, positionY, colorR, colorG, colorB`.

* fix SpriteRenderer for multiple webgl renderers, fix tests, add "withGL"

* isWebGLSupported renamed to withGL

* Added legacy option to webGL renderer

Setting ```legacy``` to true now forces VertexArrayObjects and
MultiTexture Batching to be disabled. We also store the variable on the
renderer just incase we want to use it to force settings in anything
else.

also added a test

* remove WebGLTests as they don't work on server

* Added extra param to Application

* Adds WebGL test for legacy

* Better check for WebGL in tests

it could offer a bit little performance gains.

* limit alpha number to 255. at rendering.

Avoid alpha flickering when it passes 1.0

* added space after comma
