Add password protected entry with special status

[fzesch]

LAGeSo-staff should be enabled to enter numbers. These numbers should be treated as verified without the need for further checks.

Necessary changes

New page: LAGeSo-Eintrag

Layout

• Textarea entry field for numbers
• Small input for password (with dot protection)
• Submit button for sending to db
• Cancel button for clearing all fields

No localization of this page is needed, German can be hard coded. "Sie" on this page.

Behaviour

DB entry works as in current enter page, but in addition:

• Entry works only if password is correct, then:
• USER-field in table numbers is filled with "LAGeSo"

Technical realisation

• Passwort comparison with hashes

Behaviour and layout of display page will be described in separate issue
