Auto-generate gaddags

Need to add a user interface, but gaddags are now
auto-generated if they can't be found.

Some specific improvements here:
* FixedLengthString gained a pop_back member.
* Add code to allow v1 gaddags and v0 dawgs to work
  together.
* Change memory allocation of dawgs and gaddags to
  be dynamic (the old limit didn't accommodate the
  ridiculously large Polish dictionary in the gaddag)
* The Settings class now knows a bit about generating
  gaddags.  This will be important for giving UI feedback.
* Fixed several places using filenames which should be
  using string, not UVString.
* Dawg/GaddagFactory should have been using
  UVString, not QString.  My misunderstanding.
