Fixes network bugs and adjusts program access

[NataKilar]

Fixes a few bugs with networks and their related machinery, and adds an option for grant based program access

• Fixes mainframes going invisible after opening their panel once
• Fixes Network Locks not having their UI properly updated.
• Changes how the transfer files backend works. Now it by default transfers the file with an option for cloning the file instead. Beforehand it used store_file to add the datum to the file list of whatever was being copied to, without removing itself from the former location, which resulted in every program downloaded from a mainframe being one instance. This lead to issues like Intranet Relay Chat Client is broken #1037, which is now fixed.
• Fixes a bug where running a program without proper access would break the computer until it was restarted.
• Added an option for program access to be determined by grants through the access controller. If/when full replacement of the access system with grants occurs, this should probably be reworked., but it works for now.

Adjusted program access/grants to use the normal empty list paradigm. Also went back and adjusted programs to use lists for their required_access var, and cleaned up a couple oddities (Command and Communications and Deck Management) programs who used unique access checks that could easily be replaced.

Note to self: the report access stuff should really be converted to the main system.
