TF2Classic revision 5209

We're implementing popular community suggestions to try and improve Capture The Flag.
They are intended to make the mode faster by putting less emphasis on defense.
Aggressive teams should be able to protect their flag, but not have to do so for minutes.
Some CTF maps are unfixable, but the good ones deserve some love.

Added new convars:
o tf2c_ctf_attacker_bonus
	- "CTF players respawn faster when far away from their flag base"
	- The flag base is where the flag spawns / rests idle. This is NOT about the distance to active flags.

	- Assuming standard 10s respawn wave time:
	- Die inside minimum distance: regular respawn time of 10-20 seconds.
	- Die next to enemy flag base: very short respawn time of 5-10 seconds.
	- Dying inbetween gives a proportional bonus.
	- tf2c_ctf_attacker_bonus_dist sets minimum distance from own flag base to qualify for faster respawns.

	- This encourages players to attack more. Risky pushes aren't punished as hard.
	- Camping in intel rooms is less effective. Engineers get less time to rebuild before enemies arrive.

o tf2c_ctf_reset_time_decay
	- "Carried flags remember their reset time (instead of resetting to full)"
	- With this enabled, dropping a flag no longer sets the reset timer to a full 60 seconds.
	- Instead, a persistent 60 second timer starts when the flag is picked up.

	- e.g. dying after holding the flag for 20 seconds drops a flag that lasts 40s (not 60).
	- Pick it up again for 10 seconds, die, and there's only 30s left (not 60 again).
	- Flags do not reset while held. Minimum reset time of 5 seconds.

	- This fixes stolen flags being almost impossible to protect.
	- Enemies would rush in to touch it over and over, forcing your entire team to turtle on the flag to stand a chance.
	- Now the time you have to spend defending is limited.
	- Less extreme than tf2c_ctf_touch_return.

o tf2c_ctf_carry_slow
	- "Flags slow down their carrier"
	- tf2c_ctf_carry_slow_mult sets how much slower flag carriers move (default 75% move speed).

	- Standard FPS CTF feature. Lets players catch up to flag carriers.
	- Less reason to overcommit to defense. A stolen flag is not necessarily lost.
	- Assisting your carrier gets more important.

- tf2c_ctf_touch_return: Returning the flag by touch now shows "<Playername> returned the flag" in killfeed and grants 1 Defense point
- Tranquilizer Gun: impact now interrupts rocketjumps (or any other faster than usual movement)
