All changes:
- import the new division operator and the print function
- replace the %-formatting with .format()
- full PEP8 compliance
- major code cleanup: new function send_cmd() to send an IRC command,
split flood() function into many functions.
The messages sent from a file (or stdin) are formatted with
".format(self=self)", so that attributes from class Client are replaced
with their values. You can use for example these attributes:
{self.nick} current client nick
{self.name} the server name ('weercd')
{self.version} the server version (version of weercd.py)
The configuration file weercd.conf has been removed. Instead, default options
can be set in an environment variable called "WEERCD_OPTIONS".
A file with options can be used, then name must be given as option with a
leading "@", for example: python weercd.py @args.txt
The option "action" has been removed. Default behavior is still to flood the
client. Actions "user" and "file" have been merged into a single option
-f/--file, which accepts a file, or special value "-" to read stdin.
The script now requires python >= 2.7 (because the argparse module is not
available in python 2.6 and older versions).
A symbolic link weechat-curses -> weechat is now created (by both cmake and
configure), so that the /upgrade will work from an old version.
However, if you upgrade from an old version, it is recommended to force the use
of the new binary name with the command: `/upgrade /path/to/weechat` (replace
the path accordingly).
