Added crude lines support to WebGLRenderer.

As expected, performance of one-to-one conversion from CanvasRenderer was horrible, so I had to change a bit how lines are handled.

Line object now has "type" property:

    - default type is "THREE.LineContinuous" which should behave as before: geometry represents one continuous line (v0 ... vn)

    - new option is "THREE.LinePieces" which tells renderer that geometry represents collection of individual line segments (v0,v1) ... (vn-1, vn)

(one Line object corresponds to one VBO)

(same limitations as with meshes - once VBO is baked, no changes are possible except object transforms - scale / rotation / position)
