Revised version
*) drops the separate 2-part and 3-part dotted version number variants and 
uses a regexp to tell the difference internally
*) still uses 2 as the logarithm to partition major, minor, patch version 
numbers - versions up to 99.99.99 work with this.
*) simplifies the success semantics to use a FOO_VERSION_OK set true on 
success like MACRO_ENSURE_VERSION.  - I didn't bother with the ARGN method of 
including a variable args list.
*) Moves the documentation to the top of the file. I wasn't sure about the 
right format so I imitated the other kdelibs cmake modules' documentation.  I 
don't have cmake CVS here to test doc generation as mentioned in 
http://lists.kde.org/?l=kde-buildsystem&m=119024325018579&w=2
