Epsg-hsql (geotools) project had to be modified in 1.9 version in order to
fix #777 bug (from gvSIG TRAC). As geotools JARs were not versioned in our
SVN repository, I had to guess the version (I used geotools 2.1.1).
The resulting JAR (geotools-epsg-hsql-2.1.1_gvsig.jar) replaced 'db_epsg.jar'.

Changes from original 2.1.1 version of Geotools:
