Item11267: Make release naming more flexible.

Can't assume that the version number is the same as the release number.

Item12310: Prepare for next release candidate

Note that this resets the Foswiki version from v1.1.7_004 to v1.1.6_004.
This reflects the 4th "alpha" build based upon 1.1.6. When the next
release it built, it will be:
  VERSION v1.1.6_005,  RELEASE Foswiki-1.1.7-RC4
