CHANMODES parameter in ISUPPORT is parsed incorrectly

New submission from ChosenOne <None>:

The CHANMODES parameter is currently parsed incorrectly by ''isupport_CHANMODES''.
The modeline is a comma-seperated list of letters, which gives you modes who require:
- an address on setting and unsetting
- a parameter on setting and unsetting
- a parameter only on setting
- no parameter at all.

(i.e. ('addressModes', 'param', 'setParam', 'noParam'))

Currently isupport_CHANMODES will disregard the comma and stuff all the modes into a dict which results to wrong output.

Instead, we should split the CHANMODES parameter at the comma and then build a dict according to the elements we get.
