#139 some bugs

[svilen]

1. If the programme is closed maximized, the next time
when it starts it is not maximized. Althought it seems to
work like it is maximixed becouse there is no button for
maximization, instead there is a button for restore.
2. The links in about window open the root directiry
where the programme is installed, not the internet
homepages.
3. No unicode support for cyrillic characteristics
