Allow sending special messages by prefixing them with a slash or a space

This allows you to send messages starting with / or messages like s/a/b/
and +:test: as normal text messages instead of performing the action
they normally would. This is done by prefixing the message with a slash
(/) or a space ( ), and then the prefix character is removed from the
resulting message.

Allowing / as a prefix, so you can write e.g. //slack is the normal way
to send messages starting with / in weechat. This will work for all
messages starting with a slash, but won't work for e.g. /+:test:, as
that is interpreted as a command. Using space as a prefix is the way
Slack does it. This will work for all messages.
