Polish translation for ERPNext - 636 words (+2%) part 1

This is my 1st part of translation of ERPNext.
The project consists of one file. At the beginning of the file there were a lot of sentences with English label. These labels are between quotation marks. It looks like field from the datebase and I decided to not translate these labels.
