Master

*-Add calls to remotio

 -Write more meat into the pseudo-code main() to pull everything together

 -Write a stub for getting info from the tarball/validifying the tarball. Read distren-job.xml, a file in the tarball, to find out 1. which rendering system to use (that system, e.g. blender/povray, can read more specifics, such as name of file to pass to blender and frames. Options common between different systems will be handled in common as best as possible)

 -Write a stub for publishing file and constructing job description so that the job can be shared

*-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

=-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)

*-Fix line 194 (call to myjob struct that fails miserably)

B-Add tmpdir variable (just like the datadir variable) that is compile-time or whatever

*-Add code to delete old jobfiles (maybe based on timestamp, etc... make sure they're uploaded first)

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
