Version 0.3.4 released!

[André Wagner]

The version 0.3.4 was released! A few important changes got in this
version:

* the xsw2pdf tool was replaced by xswconv, that generates
presentations in other formats. For convenience, the xsw2pdf, xsw2png
and xsw2jpeg link to this tool.
* a -s option was added, where the user can specify the starting
slide for the presentation.
* the xsw window now has a icon.

A few bugs were also fixed.

* the main one was a problem that crashed/hanged xsw when loading a
new presentation. A big part of xsw had to be rewritten to fix this
bug.
* when xsw enters *developer mode* in fullscreen, the mouse is now
visible.
* corrected a bug that prevented developer mode to work.
* corrected a bug that prevented gradients to work when the amount of
red of the background and the gradient was the same.
* corrected a bug that increased CPU usage in developer mode.

Special thanks in this version goes to Hans Christian Woithe, that
contributed with many patches that fixed the bugs above.

Regards!
