Support OpenCL source code (.cl files)

OpenCL source code needs to be compiled at run time, and thus needs to
be passed as string to the OpenCL run-time library. This makes writing
OpenCL source code inconvenient.

This patch adds *.cl as supported file type to Cactus. *.cl files are
transformed into globally visible strings, with a name consisting of
the thorn name and file name. These strings can then be easily used at
run time to build and run OpenCL code.

Since *.cl files are converted to strings (and are not OpenCL-compiled
at build time), there are no CL* options specifying compiler type,
compiler flags etc.
