[bot-10] respawn configured bots / part 2

[d47081]

Update for PR #422

Removes bot state reset on bot thinking, also the kicked state was changed from BOT_IDLE to BOT_NEED_TO_RESPAWN

I think this model more useful in bot container and looks not conflicting with it logic.
That allows to respawn configured bots only (from queue not from default BOT_IDLE slots registry)

Solution looks stable, but please let me test it for few days before merge.

Well, in last commit have fixed players online counter and make code optimizations:

1. fixed online counter as bots generated in wrong quantity after player disconnect / map rotation events
2. removed duplicated construction with BotCreate - as calling twice
3. renamed count variable to online as more clear, defined it also on init with integer data type
4. fixed bot_check_time as found the loop never stops - it reduces the CPU load

After this commit I need additional time for tests, it looks better just doubts that everything stable.

Last 2 commits includes:

• bots quantity fix on map change (before it was more than configured in max_bots, this bug was depended of real players quantity in previous session)
• added respawn event on map rotate (forgot to add in previous commits)
• initial CBot::Spawn state now BOT_IS_RESPAWNING instead of BOT_IDLE / is_used is TRUE

testing..

Everything works, but I found bots and players sometimes freeze / stuck - maybe after disconnection.
It happened on high online and/or session is closer to map rotate.

I think this problem related with slot.state changes, it's not frames or CPU issue as debug of timing works well.
