Change problematic forms to use POST instead of GET

[Nicklas Nordborg]

Problematic forms are forms were the generated GET url get's too long for the web server. This usually results in an server response similar to:

Request-URI Too Large
The requested URL's length exceeds the capasity limit for this server.
Apache/2.2.8 (Unix) mod_jk/1.2.26 Server at base2.thep.lu.se Port 80

(In [4506]) References #1118: Change problematic forms to use POST instead of GET

I have changed most of the forms I could find to use POST instead of GET. Many of them are probably not problematic, but I found some:

• Form for JEP extra value calculator plug-in
• Form for JEP intensity transformer plug-in

Closing this so we can release 2.8.2. Open a new ticket if more forms with problematic behavior is found.
