This commit takes a pass at the implementation files in opm-common and removes references to libecl functions where practical. In particular we switch to using types from C++'s standard library (and Boost.Filesystem) to achieve the effects of the interfaces being replaced. We also insert direct calls to Posix function fnmatch() to preserve existing pattern matching behaviour (well lists and well templates).

Contains common components used throughout all of OPM, in particular CMake modules for the build system.
