Revision 401313

science/mcstats[-comps]: update 2.1 -> 2.2a

- Update PORTVERSION and distinfo to 2.2a
- Simplify DISTNAME/DISTFILES/MASTER_SITES/WRKSRC handling
- Clean up language in COMMENT (mcstas-comps only)
- Use PORTVERSION in PLIST_SUB and %%PORTVERSION%% in pkg-plist as
  as port installs self-contained under ${PREFIX}/mcstas/${PORTVERSION}
- Add pkg-install/pkg-install to SUB_FILES and rename appropriately
- Use PREFIX in pkg-install.in/pkg-deinstall.in
- Remove the post-fetch routines
- Switch unnecessary bsd.port.(pre|post).mk include to just bsd.port.mk
- Sync pkg-descr verbiage between ports and wrap at 76 characters
