Remove unused logo from Makefile.in
Bump version to 1.3
Fix #82: Make /msg shortcut use the unstyled nick.

When messaging a user, the original nickname is required - as
opposed to the escaped, abbreviated and possibly parenthesized nickname
displayed on the page.
Break lines in <code>
Maud is extremely amused. Or possibly furious.
Add --style arg to configure.

Also, set default stylesheet in static markup, hopefully
fixing some more mobile browser issues (*cough*Apple).
Fix #81 (I hope): replace rsync with cp.

The cp command is wrapped in a macro, so it can be
overridden by setting the CP environment variable.

Also tearing out the "core" target, which copies JS core sources
to the build folder. It's not referenced anymore, and in any case
I think it's obsolete since both aggregation and installation go
for the source files directly.
Fix #79: Avoid duplicated history on rejoining.

The xmpp module now tracks incoming messages, and cuts off
the room history when rejoining a room to avoid duplicates.

Note: This feature very much relies on client and server
time being synchronized.
Heavier lines on maud emote.
Fix #58: Block recursive aliases from being created.

This doesn't rule out other shenanigans, since it is possible
to achieve n^m complexity through m macros of length n, but
at least this will guarantee the macro halts.
(Aside from users messing around with the console, of course.)
Actually create prefix folder, in case of CDN.
Use the CDN url for the logo image.
Modified the logo yet again.

Not satisfied yet, but whatever.
Add the logo svg source to the repository.
Fixing the lower logo border.
Now that recursion is blocked, executeMacro should be safe.
It *should* be impossible to exceed the stack size with
non-recursive macros, even if they are very deeply nested.
