*-charsets: the program should operate in UTF-8. This is partially required by libxml2's (and XML's) usage of UTF-8. We want the program's internal charset to be UTF-8 and figure out if we need w_char/whatever to fulfill UTF-8. I don't believe we do... mabye we just need a declaration that al data stored must be in UTF-8 format.

 -rename some struct members and variables to be more program-agnostic and more sensible (e.g., no blender-specific stuff)

Slave

 -Fix current bugs

*-Add calls to remoteio, once it works or even before it works

*-Other XML-writing/reading

=-Make code more flexible for different types of jobs and operating systems (such as paths, libs, etc)

 -Add code to allow pausing/resuming of the slave (including a running blender process)

 -Add a threads variable for software that doesn't support threads (blender takes care of this by itself)

Options

 -Rewrite some stuff, try to make it simpler

x-Move server and client confuse code into their individual files, rather than in the common file. -- note: there wasn't any client code in options.c. There was the ``server'' section. That section is passed multiple times and provides information to remoteio on how to connect to servers

 -Review all confuse interfacing

 -Push patch for relative includes in confuse to the confuse developers
