[osis-core] morph regex error

[Troy A. Griffitts]

Hey guys.  It seems we may have messed up the regex on the morph 
attribute of <w>.

Here my line:

<w xml:lang="grc" lemma="strongs:15" morph="robinsons:V-PAM-2P" 
xlit="la:agaqopoieite">GREEK UTF8 TEXT HERE</w>



Here's the MSV error output:

Error at line:279, column:117 of file:///space/home/scribe/msv/./lexcounts
   attribute "morph" has a bad value: the value does not match the 
regular expression 
"((((\p{L}|\p{N}|_)+)(\.(\p{L}|\p{N}|_))*:)((((\p{L})|(\p{N})|_)+)(((\.(\p{L}|\p{N}|_)+)*))?))".
