Allow xcode 6.0.1 to update the OF project and the OSX project template
adds fixed function vertex attributes

+ leaves programmable path as is (everything but for indices is an attribute)
+ adds fixed function vertex attributes for fixed function pipeline
+ this keeps the promise intact that a buffer location == shader attrib location
+ keeps the programmable path clean so that when we deprecate the fixed function pipeline eventually, we can do this by only removing a couple of if branches.
+ caches programmable renderer test for speed and stability

Fixing mistake sneaked in #3371
better caching for isProgrammable

+ query isProgrammable once, keep as static bool for all to see.
+ since it's impossible to have a fixed function and a programmable context within one app, the check only needs to happen once, even a rendererCollection must be homogenous in this respect.
update checks for fixed function renderer

+ makes sure fixed function renderer checks for usingVerts rather than the position attribute when issuing draw commands.
+ uses fixedFunctionPositionAttribute to draw when using fixed function.
add vao checks to fixed function helper methods

+ ensure VAO availability is checked before helper methods set vbo data
fix renderer check

+ ensures renderer check only happens *after* renderer has been initialised.

Since there are lots of static `ofVbos` and `ofVboMesh`es floating around, these get initialised before the actual renderer does. This makes sure to perform the renderer check only after the renderer has been initialised.
