Delete all fragments which belongs to a user upon deleting

[int2001]

While testing on my instance i recognized a lot of old QSOs and other fragments where still in Database active.
In preparation of activating contraints somewhere in the future, we should delete everything which belongs to the User.

Affected Actions:

• Delete User (should delete everything from the user: OQRS, Certs, QSOs, eQSLs, QSLs, bandx, stations, logbooks, etc.)
• Delete Station-Location (should delete everything from the station: OQRS, QSOs, eQSLs, QSLs)

Works great :)

Tested with the following result:

• Emptying log table works
• Emptying banduxer table works
• Emptying user_options works
• Emptying lotw_certs works
• Emptying station_profile works

Not working:

• Emptying eQSL_images
• Emptying qsl_images

Confirmed. (e)qsl_images tables are now emptied as well.

Rest also tested. Deleting station_location removes connected data.
Removing single QSOs also removes relevant stuff from DB and file system.
Good to go.
