Synonyms processor text field error

So I see there is a validation of the field, but for some reason, it's not working. Will check it out.

From the code, I see that the desired functionality is the second option in the proposed resolution. So I'll go with that option.

The issue is still present if you for example type spaces into the text area or for example put spaces, press enter to a new line, put a few more spaces etc. and then save the form.

Found that empty lines also passed validation and would cause parsing errors. Now empty lines (lines containing only \n, \r, or \r\n) will cause validation to fail, lines containing only spaces also now don't pass validation.

Rebased and merged, thanks.
