* src/sample: Update manpage, sample config and sample bip.vim + typo 

* src/bip: warn the user about rlimits upon start and whenever they're
reached
* src/bip: add -v flag (show version)
* src/bip: add admin option to user block, and restrict some commands to
admins. Log whenever a /bip command is used
* src/bip: enhance /BIP LIST and HELP commands, add INFO command
* src: fix defaults user/nick/realnames not loaded into connections,
resulting in segfault (WRITE_LINE1 to NULL) and oidentd.conf file not
containing usernames
* src: add default.h and version.h
* src: fflush() system log every log_sync_interval
* src/bip: fix "Resetted." printed whenever a client talks with
backlog_reset_ontalk true
* src/bip: fix backlog user options not set to defaults in add_user
* src/bip: fix oidentd.conf config written lately. Still some issues
* src/util: add human readable time hrtime(), bool2text() and ssl
checlmode2text() functions
* src: lower RECONN_TIMER + add RECONN_TIMER_MAX option
* src/bip: code some validate_config
