Added the initial version of Tibbibl, which Nathaniel Garson of UVa

e-mailed to me.  Tibbibl is an editor for XML-based bibliographies of
Tibetan texts.  All I did was change the package from org.thdl.xml to
org.thdl.tib.bibl and add boilerplate; no changes to Than's code were
made.

Tibbibl features a diacritic input tool which Jskad might want to
swipe.
