gridtool fixes
contur-gridtool has some problems:
- looks for the db file in the cwd. Should probably look in the ANALYSIS directory instead
- if it doesn't find the db, the file scan fails as below:
INFO - Could not get info from DB. Will use file system instead.
Traceback (most recent call last):
