Fixes #5570

Also de-copypasted charger code, as i had the opportunity.
Fixes #5553

Camera network key itself is useless without security camera program. Created hidden version of this program and added it to each laptop. In short: it works.
Fixes #5569, Fixes #5571
- Reworked card reader code, it's cleaner and less copypaste now
- Updated medical records, security records and HoP card computer to work with the update. It's however possible i missed something, can't go through all computers in game. Tell me if you find something that's broken due to this, i will fix it ASAP.
- Security records color for "none" security status changed a bit so it doesn't burn eyes of anyone trying to  read it (issue #5571 - white on light green? Bad choice imo)
- Multi-card readers now actually WORK for laptops. This includes security records (issue #5569) and medical records (same case, just not reported). You still have to insert your card into read slot, if you insert it into wrong slot notification will be shown that you should use read slot instead of write one.
Fixes #5572

- Detective-vended laptops now have medical records program installed.
Fixes #5670

- This also includes other vending machines than laptop vendor. They now actually take money from your account instead of pretending to do so and giving stuff for free. No moar spess communism.
- Vending machines now ask for PIN code only if your account settings require it (ie: Security levels 1 or 2. Default is 0 - only ID card swipe)
