Provide method for updating catalogue based on recurring date/time, or command line argument to force update

[gazzat5]

Is your feature request related to a problem? Please describe.
Running the catalogue updates every x minutes is inconvenient and wasteful of resources and means that my PC can both be slowed down when I need to use it, or that it attempts to index mapped network drives that are not mapped because my vpn is disconnected

Describe the solution you'd like
Ability to schedule catalogue updates by recurring date for example with the following types of schedules available:
every 24 hours | at 00:00 every day | at 00:00 every thursday | on the 1st monday of the month at 00:00 | etc
either in the program via an update to the options page, or more simply by implementing a command line argument like --update to trigger a catalog update (on the command line/without opening the GUI), that can then be scheduled by the OS's built in scheduling functions (crontab, windows scheduler)

Describe alternatives you've considered

1. A command line argument to trigger the update manually
2. Expanded Built in options to schedule the update in the program options
