Sebastien Helleu 9222a7b109 Added group support for nicklist, fixed some bugs in plugins API and IRC plugin 
Added group support for nicklist (with subgroups).
Partial changes in IRC protocol functions (new arguments with argv and argv_eol).
Fixed some bugs:
- nicklist in plugins API
- problem in main loop with select() when SIGWINCH is received (terminal resize)
- bug in string explode function
- bug in infobar countdown.
