- no GUIDs in chat for players or portal details - so remove player GUID related functions
- remove player guid code from COMM
- update portal_info functions to compare to player name rather than guid
IITC relies on this being available early, but the new sessionStorage for player name cache means it often isn't
(still, it's not perfect - as IITC still requires a lookup from guid->name for us to store the reverse mapping - this has always been a theoretical issue though)
likely fix for #577
this gives a simple method of expiring entries. also, prevents localStorage from filling up with thousands of player names over time
(ideally something controllable with configurable age should be used, but this was a quick and simple change to try first)
if more are to be resolved, multiple requests are made. this does increase the odds of hitting the request rate limit, but in that case we'll get http failed requests and the names will be pushed back onto the pending resolve list for next time
fix#323
