Added required dependencies on opm-parser and CJSON
Added very simple parser test to check a parser can be instantiated and a simple file parsed
Set the boost version requirement to 1.44 - and added cJSON dependency
Removed explicit cJSON dependency from opm-core
Added CJSON_INCLUDE_DIRS to OPM_PARSER_INCLUDE_DIRS
Raised the opm-core boost dependency to 1.44 to reflect parser requirement
