Replaced unixid with uid-/gidnumber (glauth v2.0)

[zeo101]

Hey Nils,

since glauth v2.0.0 complains about unixid being deprecated I replaced it with uidnumber and gidnumber accordingly.

To be consistent, I also changed the db column names in the group and user table.
So if you have an existing setup, you need to rename the sqlite columns using dbeaver for example.

hey thanks for the info and the code.
Haven't follwed glauth development in the last months because i was pretty busy in my day job and the system just worked but 2.0 introduced a lot of other useful features (users.capabilities and behaviors) which should be configureable in the ui.

It might be possible to create a migration script which does this automatically.
Another solution would be a warning on startup that detects the old db scheme and prompt fo manual upgrade (maybe with a small python script which will do this automatically.

Well lots of stuff do do here :)
I will soon merge this in a dev branch and start working on glauth 2.0 compatibility. I have some free time before christmas and this is a chance to dust of my dev environment!

Ok i merge your pr into a new branch (glauth-2.X), here i also updated the python environment (3.9) and all libraries.
I am still working on a migration script.

We should be able to alter the table names with the following in the flask migrate file See Commit:

def upgrade():
    op.alter_column('user', 'unixid', nullable=False, new_column_name='uidnumber')
    op.alter_column('group', 'unixid', nullable=False, new_column_name='gidnumber')
    # TODO foreign keys

But we also have to update the foreign keys in the user, included_groups and othergroups_users table. This is definatly possible but i haven't figured it out yet to do this without losing any existing data/connections.
