(for the example I will use [b] as irc bold char and [i] as italic char)
In case we got text like:
"aaa[b]bbb[i]ccc[b]ddd[i]"
we used to generate
"aaa<b>bbb<i>ccc</b>ddd</i>"
which is invalid HTML, as the italic has to be closed before the bold,
as expected the result also looked wrong(on the screen).
What I do now is to remember which tag is open and reopen it,
so I will generate text like:
"aaa<b>bbb<i>ccc</i></b><i>ddd</i>".
-move html stuff out of common.cpp/h
- support the \x16 reverse char, inverts default fore- and back-ground colors
