Reset disassembly/reflection of shaders when recompiled. Refs #470

Browse Source 
* In GL various really really stupid options for changing shaders and
  recompiling and relinking is possible.
* We don't support the whole giant trash fire, but we can at least
  handle re-compiling a shader within the same program (so the original
  source isn't used anywhere and can be safely rewritten).
