purge & purge history
For people with configuration access, add the option to:
- purge the dictionary, i.e. remove entries
- purge the history, i.e. remove the changelog
The latter is quite important: a rather small dictionary of 500 entries builds a database index of 2GB because of the history log after some 20 re-imports of the data.
The option of purging history should be thus available also on the import screen.
In both cases, the database should be also VACUUMed.
These links should be added alongside deleting of dictionary into the configuration screen.
"import.py -pp" purge history
add config option
yes thanks -- the user screen should, when you choose to purge, now also offer to purge history, and in that case run the import with "-pp".
