v 1.0.9

With two major fixes:

• For sources like tvgids.tv that use an offset in their url that gets updated somwhere in the early morning resulting in wrong programme dates.
• For sources like npo.nl that need data from a detail page to determine a proper stop-time. They now if set as prime_source do grab the detailpages prior to starting the merge process. You can disable this behavior, that can lengthen a grab, by either making sure that this source is not set as prime_source or by setting the new option "pre_merge" in your configuration either global or for single channels to False.

With some minor fixes especially concerning the database
With two new start-up options:
--clear-source <sourceid>
--clear-channel <chanid>
to either remove all programme data from one source or one channel from the database.
You can use it to remove the faulty data from tvgids.tv while leaving all other data intact.
tv_grab_nl3.py --clear-source 1

And a fix on the --use-only-cache option that also conflicts with the new "pre_merge" mode. So using --use-only-cache disables the new "pre_merge" mode.
