Bump ParamCap to 254

Apparently IRCds have decided that the 15-parameter limit doesn't matter
anymore. 254 is the maximum number of single-byte parameters (following
a single-byte command) which fit in a 512-byte CR-LF-terminated line.
When everyone decides that the 512-byte line length limit doesn't matter
either, I will delete my software and people can use some JavaScript
garbage instead.

This makes struct Message 2080 bytes, but there's only ever one or two
of them around at once. Avoid passing it by value to handle.
