update Forces to v0.4: mo_message and mo_os usage refactor

Fixes #238 (closed)

• update FORCES to v0.4.0
• mo_os routines have a new interface (chs/forces!72 (merged))
• use error_message when possible
• all messages done with mo_message
• added command line option for silent mode (--quiet / -q)
  • can be repeated to suppress normal messages and then also error_messages
• command line option short-name for version was change from -v to -V (-v is reserved for verbosity by the parser)
