Holopads (#32711)

* Initial resources commit * Initial code commit * Added additional resources * Continuing to build holopad and telephone systems * Added hologram shader * Added hologram system and entity * Holo calls now have a hologram of the user appear on them * Initial implementation of holopads transmitting nearby chatter * Added support for linking across multiple telephones/holopads/entities * Fixed a bunch of bugs * Tried simplifying holopad entity dependence, added support for mid-call user switching * Replaced PVS expansion with manually networked sprite states * Adjusted volume of ring tone * Added machine board * Minor features and tweaks * Resolving merge conflict * Recommit audio attributions * Telephone chat adjustments * Added support for AI interactions with holopads * Building the holopad UI * Holopad UI finished * Further UI tweaks * Station AI can hear local chatter when being projected from a holopad * Minor bug fixes * Added wire panels to holopads * Basic broadcasting * Start of emergency broadcasting code * Fixing issues with broadcasting * More work on emergency broadcasting * Updated holopad visuals * Added cooldown text to emergency broadcast and control lock out screen * Code clean up * Fixed issue with timing * Broadcasting now requires command access * Fixed some bugs * Added multiple holopad prototypes with different ranges * The AI no longer requires power to interact with holopads * Fixed some additional issues * Addressing more issues * Added emote support for holograms * Changed the broadcast lockout durations to their proper values * Added AI vision wire to holopads * Bug fixes * AI vision and interaction wires can be added to the same wire panel * Fixed error * More bug fixes * Fixed test fail * Embellished the emergency call lock out window * Holopads play borg sounds when speaking * Borg and AI names are listed as the caller ID on the holopad * Borg chassis can now be seen on holopad holograms * Holopad returns to a machine frame when badly damaged * Clarified some text * Fix merge conflict * Fixed merge conflict * Fixing merge conflict * Fixing merge conflict * Fixing merge conflict * Offset menu on open * AI can alt click on holopads to activate the projector * Bug fixes for intellicard interactions * Fixed speech issue with intellicards * The UI automatically opens for the AI when it alt-clicks on the holopad * Simplified shader math * Telephones will auto hang up 60 seconds after the last person on a call stops speaking * Added better support for AI requests when multiple AI cores are on the station * The call controls pop up for the AI when they accept a summons from a holopad * Compatibility mode fix for the hologram shader * Further shader fixes for compatibility mode * File clean up * More cleaning up * Removed access requirements from quantum holopads so they can used by nukies * The title of the holopad window now reflects the name of the device * Linked telephones will lose their connection if both move out of range of each other
