JohnWildkins 616776f886 Modular PDAs: The End of an Era (#10319) 
PDAs are dead, long live PDAs. All trace of old PDAs has been scoured from the codebase, and in its place are modular computer PDAs that are feature-equivalent. Essentially every PDA function except the Syndicate detonation feature and Notepad has been ported over, and battery life for handheld computers has been boosted alongside the addition of charging cables to make things easier.

/*
Asset cache quick users guide:
Make a datum at the bottom of this file with your assets for your thing.
The simple subsystem will most like be of use for most cases.
Then call get_asset_datum() with the type of the datum you created and store the return
Then call .send(client) on that stored return value.
You can set verify to TRUE if you want send() to sleep until the client has the assets.
