#1 program crashes when processing last thought

[Tim Hemel]

If I am in the thoughts screen viewing an individual thought, and I delete or process it, so that the thought list that should be displayed is empty, the program crashes. Instead, the thought list view should be restored.

Reproduce: add a thought, press enter to view it, then press 'd' to delete it, program crashes:

File "tmttd/IndexedList.py", line 28, in getCurrentIndexedObject
return self.objects_list[self.object_index] IndexError: list index out of range
