Description field allows more characters entered than is stored

[netniV]

Describe the bug

If you modify a device, such as Localhost, and give it a seriously long description by repeated pasting ' extremely' to fill the maximum length, then change the last two to be ' long description', the long description part will not be saved.

Expected behavior

All the description should be saved by ensuring that length of database meets length of field

[TheWitness]

This problem is actually larger than you may think. We should have a project in the 1.3.x timeline that audit's the forms for the column descriptions, or we should deprecate "max_length" and just set it to the database column size. Easier said than done I imagine.
