perltidyrc with minimal amount of changes to code

Based on the recent irc discussion i made a .perltidyrc file which results in the minimum amount of changes i could configure it for.

The bulk of the changes it does is vertical alignment in lines with similar content, and indenting of qw statements. As you go through you'll however also find that it improves some parts of the code to make them more consistent.

Might be worth taking this in, as a one-time thing and asking people who make patches to tidy the code with the included perltidyrc in the future.

If you don't like it, no worry, i won't cry. :)
