[SoC] Status of imagemosaic-jdbc plugin

[Christian Müller]

This week I did some bugfixes and solved the x-Axis Problem (log/lag, which 
is the x and which is the y). 

I did a test inserting a layer of Austria with 8 pyramids, using 28 sql 
tables in db2 , image data has about 20 GB. Works fine, I checked the 
results with geoserver. 

I restructured some things which I discussed with my mentor. (performance).
