Log Message:
update to 0.14.

we use a shared sqlite, but new-sqlite can read old-sqlite files for
users of monotone 0.25 which still uses the pre-3.3 internal sqlite.

>From the NEWS file:

0.14:
- support new format of monotone db (using BLOBs instead of base64 encoding)
  /!\ these newer monotones (after 0.26pre2) use sqlite 3.3, if you're building
      monotone-viz with a shared sqlite lib, make sure it is compatible !
- display a nice dialog when the database is locked (e.g. during netsync)
- when a revision has a tag cert, use it as label instead of the revision's id

0.13:
- support monotone 0.26pre1 (it still works fine with monotone <= 0.25)
- stop displaying `disapprove' nodes in a special way (this allows a faster
  loading of the database)
