[Tora-develop] Source code cleanup

[Petr B. <ben...@gm...>]

Hi, is there any objection against this:
https://github.com/tora-tool/tora/pull/5

The justification for this is that right now there is a number of
various code styles (Allman, Linux, K&R and so on) used across the
code as well as mixed space and tab indents and similar differences,
which makes the reading of whole source code pretty hard.

Most of open source projects usually follow some coding style which
defines how the source code should be written. Tora doesn't have any,
but I found that most of code, I guess more than 80% of it, uses some
kind of style that resembles default of Visual Studio (I suppose
original tora was written in it). So I created an astyle format that
follows that and formatted all source code files with it, so that it's
consistent everywhere now.

If there isn't anyone against that, I would like to merge this into master.

Thanks
