[Taler] Documentation patches

[Florian Jung]

Hi everyone,

I just started tinkering around with GNU Taler a bit, and it appears I 
started right away into the new 0.9 version :D.

However, the documentation at 
https://docs.taler.net/taler-exchange-manual.html has some minor issues 
which I fixed in my local working copy when I noticed them. Now I wonder 
what would be the best way to actually submit these patches. Going 
through that copyright agreement process seems a bit tedious for just a 
couple of changed lines in the documentations. Is it required or is 
there an easier way?

Cheers,

Florian
