description:
Cleanup in cache system. Added test19.py which tests building and rebuilding with cache in several ways.

Behaviour of build_module is as follows:
- If modulename is provided, no cache is used and the module directory is placed locally.
  However, the module is not rebuilt if the checksum of the files is the same as last building.
- If signature is provided, it should be an identifier for the whole module configuration.
  That is, it must include information about the compilation flags etc.
  Otherwise, import_module(signature) wouldn't be possible.
  This mode is what FFC and SFC will use.
- If no modulename or signature is provided, a signature is computed from the checksum
  of all arguments and user-supplied files (i.e. not including the instant-generated files like setup.py).
  This mode is used by the inline* functions, and may be the best choice for dolfin.compile_function.

description:
Cleanup in import_module, extracted multiple layer memory cache
to separate helper function. Now the signature is used as the
module name if it is a valid filename shorter than a constant
length (currently 100), and a checksum is computed from it otherwise.
TODO: Must use this helper function in build_module for consistent behaviour!
