Permit modification of existing entries

[njloof]

Is your feature request related to a problem? Please describe.
Sometimes the information entered into the meeting attributes or summary is incorrect; it would be useful to be able to edit both of these areas.

Describe the solution you'd like
It should be sufficient to use editing capabilities within the console to make modifications.

Describe alternatives you've considered
I've considered going into the database and hacking the information there.

Additional context
It would probably be a good idea to make this capability optional at configuration time, so that use cases that do not want entries to be modified or deleted for auditing purposes can simply turn off the capability.
