Many fixes and improvements

[NexiusTailer]

• Fixed bypass when cheaters could send a death + requestclass (noping at the same time any attempts to be spawned by the server) and become technically still dead but no more desynced (FreezeSyncPacket was disabled and they might start sending onfoot or other updates)
• Minor fixes for magic numbers in special action IDs
• Accessing internal variables directly instead of external API functions in a couple of places (those getters which were just returning a variable value but also have validation checks which anyway will always be passed and thus have little sense using them inside the lib itself)
• Fully fixed #238
• Force switching weapon to slot 0 done properly in every place
• WC_IsPlayerPaused moved to the right section
• Other minor fixes and corrections

Btw, these issues probably aren't relevant for now and can be closed:

165, #183, #201 (was fixed in #207)

Looking good, I don't have any complaints.

Is the healthbar dimensions fixed to the point where those issues could be closed then?

[NexiusTailer]

They can be closed, yes. Healthbar now already uses LD_SPAC:white instead of regular box (like it was suggested in one of the issues) and uses precise coords since some fixes in #207, so it's ok at the moment on the most resolutions:

(it looks pretty good on other resolutions too, I just sent the most popular to ensure they're good at first)
