full vector functionality for vertexArray

[Vovosunt]

Just thought, since vertexArray is basically a vector<Vertex>, why not add all the functionality, like insert, remove and so on.
It's really easy to do and quite damn useful 

Also a side question: do all the vertices in the draw call get stored into a VBO?

Why don't you use a std::vector if you need all its functions?

do all the vertices in the draw call get stored into a VBO?

No.
