Light Cache file name using camera name/frame value

[JuhaW]

Is it possible to add same kind of option for Light Cache autosave/from file than image save has, using $F $C.
1) ($C) Simple example: using 2 cameras, and it adds active camera name to light cache file name. And when using from file option it knows what to load.
2) ($F) Simple example: using one camera, camera loc/rot frame 1 and 2 and it adds frame name to light cache file name. And when using from file option it knows what to load.
