Move current love.graphics.setStencilMode functionality to setStencilState.

Browse Source 
Add new higher level love.graphics.setStencilMode function.
- Add love.graphics.setStencilMode(mode [, value = 1])
- Add love.graphics.setStencilMode().
- Add mode, value = love.graphics.getStencilMode().

The possible modes are "off" (same as no parameters), "draw", and "test".
The "draw" mode disables color writes and sets the stencil state to ("replace", "always") using the given value.
The "test" mode enables color writes and sets the stencil state to ("keep", "equal") using the given value to compare to.
