Added m_repeat - Allows for blocking of similiar messages

Changes to the original module:
- Parse settings using a sepstream, accept remote mode changes regardless of our config
- Refuse to link when config settings differ
- Style changes

All ideas and features are the brainchild and work of Daniel Vassdal

+# A module to block, kick or ban upon similiar messages being uttered several times.
+# Syntax [~*][lines]:[sec]{[:difference]}{[:matchlines]}
+# ~ is to block, * is to ban, default is kick.
+# lines - In mode 1 the amount of lines that has to match consecutively - In mode 2 the size of the backlog to keep for matching
+# seconds - How old the message has to be before it's invalidated.
+# distance - Edit distance, in percent, between two strings to trigger on.
+# matchlines - When set, the function goes into mode 2. In this mode the function will trigger if this many of the last <lines> matches.
+#
+# As this module can be rather CPU-intensive, it comes with some options.
+# maxbacklog - Maximum size that can be specified for backlog. 0 disables multiline matching.
+# maxdistance - Max percentage of difference between two lines we'll allow to match. Set to 0 to disable edit-distance matching.
+# maxlines - Max lines of backlog to match against.
+# maxsecs - Maximum value of seconds a user can set. 0 to allow any.
+# size - Maximum number of characters to check for, can be used to truncate messages
+# before they are checked, resulting in less CPU usage. Increasing this beyond 512
+# doesn't have any effect, as the maximum length of a message on IRC cannot exceed that.
