 | Ghostchat for AMX

 |
 | Description: Plugin to let dead people read what alive people say
 | or to let dead and alive people chat with eachother.
 | You can also make only HLTV read chat of the living.
 | Plugin can be disabled from any console by an admin.
 |
 | Commands: amx_ghostchat 0 // Plugin disabled
 | amx_ghostchat 1 // Dead can read living
 | amx_ghostchat 2 // Dead and living read eachother
 | amx_ghostchat 3 // Only HLTV can read the living
 |
 | Access: Everyone can use amx_ghostchat to retrieve status
 | Admin Level B needed to _change_ ghostchat status
 | Server console access (won't give response but does work)
 |
 | Thanks to: PsychoGuard for his idea of dead reading alive.
 | [WHO]Them for making the ghostchat plugin for AM.
 |
 | Changes: Monday 2nd June 2003, v0.4:
 | - Fixed server crash (!!)
 | - Changed default to mode 3 (HLTV only)
 | - Changed log file to AMX's log files (amx/logs/admin%m%d.log)
 | Wednesday 20th April 2003, v0.3:
 | - Removed a little bug where lines starting with the
 | '[' character were ignored by the plugin.
 | - Added a [G] tag before *ALIVE* or *DEAD* so people
 | know it's the result of a plugin (some get confused).
 | - Added a reponse to any line with [G] in it, so when
 | people ask what [G] means, they get an automated
 | response asking to use amx_ghostchat for status.
 | Tuesday 29th April 2003:
 | - Everyone can use the amx_ghostchat to get status
 | - A 3rd mode has been added, 'HLTV can read living'
 | Sunday 27th April 2003, v0.2:
 | - Fixed displaying empty messages or msg's with [
 | - Changed client_print() with a real message, so
 | color gets added depending on team.
 | - Fixed bug where HLTV or clients console gets
 | f*cked due to a missing newline.
 | Saturday 26th April 2003, v0.1:
 | - First release
