Added JOGL2 Flags (README/Jake2.sh), New JOGL Renderer Order, ..

New JOGL Renderer Order, last comes first if not defined by 'vid_ref':
  - jogldummy
  - joglgl2
  - jogles2
  - jogles1

README JOGL2 Flags:

JOGL Renderer can be set via 'vid_ref', i.e. '+set vid_ref jogles2'
  - jogles1 ES1 renderer, may use GL2ES1 w/ 'jogl_gl2es1 1'
  - jogles2 ES1 renderer, may use GL2ES2 w/ 'jogl_gl2es2 1'
  - joglgl2 GL2 renderer, maybe disabled w/ 'jogl_gl2 0'
  - jogldummy NOP GL renderer to measure performance w/o GL costs

Special GLProfile selection flags:
  - jogl_gl2    0  disable joglgl2, default enabled '1'
  - jogl_gl2es1 1  allow desktop GL2ES1 for jogles1 renderer, default disabled '0'
  - jogl_gl2es2 1  allow desktop GL2ES2 for jogles2 renderer, default disabled '0'

Special drawable surface flags:
  - jogl_rgb565 1  requesting a RGB565 surface, otherwise request default RGB888 surface
