say.js needs updating to notice these and parse the new format messages

Separate the bit index from the string index in show_user_stats() so that when 'flag' is false there are no uninitialised garbage gaps left in the string.

Fixes #61

reverts the various listuser functions to a method of printing logout date that works and doesn't print the date as 1875/6 but without falling foul of the shadow warnings

fixes #62

Server will now exit if unable to open who list.
mw.spec now includes build dependency for postgresql-devel

copied function into import, should really get factored out.

Fix a couple more leaks and revert a "fix" for another leak which is causing a segfault. That leak will still have to be fixed.

Add a systemd unit for mwserv and update the spec file to fix 'make rpm' to build and install on Fedora.

Update the JS bits to API version 1.8.5 (from 1.8.0). This fixes the build on Fedora (yay). Roughly involved:
- Upgraded silver's libmozjs-dev to the one in the debian-backports repo
- Fixed the Makefile to sniff the lib version with pkg-config and work around a silly JSScript/JSObject difference between Fedora and Debian
- Lots of replacing JS_GetStringBytes calls with JS_EncodeString
- Added a few includes which are needed to build on Fedora
- Changing the signature of the js function definitions (a bit prettier now)
- Various other tweaks to satisfy the API changes

Fix some memory leaks, mainly caused by duplicated strdups now that hash_set_p does its own str duping.

- Remove the -s from `install' runs in the src/ Makefiles to stop stripping our binaries
- Add a new -dbg deb package
- Update to debhelper compat level 7 and make use of the new magic in the rules file
- Add mw3.install to tell it what files to install in the mw3 package
- Rename dirs to mw3.dirs
- Stop lintian complaining about the init script
- Etc.

Fixes a strdup(NULL) someone introduced so he could add lots of compiler warnings that somehow don't warn him he's strdup()ing NULL ;)

Remove the concept of a "Development version" since it's easy to test mw without special permissions now and the only thing it seems to change is the login banner anyway. Also fix up more unnecessary includes and externs.

Fix a logic fart in init.c and revert show_specials back to how it was before I broke it (my implementation didn't handle the gaps in the bitfield).

Remove a bunch of unnecessary includes and remove --std=c99 from server/Makefile and webclient/Makefile since --std=gnu99 is already there.

Add more warning options: -Wcast-align -Wbad-function-cast -Wmissing-format-attribute -Wformat=2 -Wformat-security -Wformat-nonliteral -Wno-long-long
Also remove create_pipe (which was left empty) and get_pipe_name (which is now unused).

Adds -Wwrite-strings and adds (a lot of) const correctness fixes. This caught some crazy things along the way such as unnecessary strdup()s and passing a char * to sqlite_free(). Some files only contained one definition called from one other file so they were merged and deleted.
