Return to development
Exclude the master branch from builds
Warn about conditional return and add script dumper

The problem is that since 'if' is a function, the 'return' action
is executed *before* the recursive return. This messes up the stack.

Sooner or later I'll be able to fix the scripting language properly,
but it's probably a good idea to goto L_Return to clear variables anyway.
Fix statup2 not actually increasing the stat
Implement out-of-tree builds
Use the One Makefile to build them all

This changes the names of the built binaries:
    login-server    ->  tmwa-login
    char-server     ->  tmwa-char
    map-server      ->  tmwa-map
    ladmin          ->  tmwa-admin
    eathena-monitor ->  tmwa-monitor

It also gets rid of the 'deps.make' file.
Install compatibility symlinks for a while
