Corrections

Updated the appendix to contain corrected Stadgar as proposed by my girlfriend. Mostly minor language fixes but two bigger ones.

### 6 - Uteslutning
A person that doesn't accept an exclusion must do a written submission to the board at latest four weeks before the annual meeting.

### 12 - Firmateckning
To make it easier for us it can be decided that everyone in the board have Firmateckning together (everyone must sign) or two board members (two must sign). My girlfriend said this is common way to do it as it makes it easier for following boards.  

The annual meeting is updated with these changes in this Pull Request. https://github.com/python-sverige/protokoll/pull/1
