Added gettex check for symbols that have a isin in the json defined
OR
direct isin lookup in process.php
Why ? Cause some depots n banks love to let you only trade on gettex to keep costs down.. for them.
Sadly there is no reliable api to go feom symbol to isin..
And the gettex compare ueses a postdata gz feom gettex website.
Hacky, but spares me having to open the app just to realize: oh. can't
