Bug in clean/rebuild and in AUTHORS file

[Maciek Wiśniewski]

Hi,

I found problem in "clean/rebuild all" option. It forgets what is set in
project options - you have to run this dialog change something and press OK,
after doing cleaning and rebuilding. Running counfigure dosn't help.

In AUTHORS file and in User Manual is bug in word : "polnish". It should be
"Polish". And others translations should be written with capital letter on
begining.

Bye,
