Add additional bank configuration items

For prettier generation of bank letters and other bits used in examples:

Expand the bank config to include:

* "bankFullName" used in the INI letter's which are sent to the bank.
* "bankShortName" used in the filename for the generated letters and in other places if needed.
* "languageCode" used for determining which template to use for the bank (currently "en" and "de" are supported).
* "storageLocation" can be used to specify a local or network path where to store downloaded files.

* In bankLetter.js: Use the current script folder as output for the bank's letter in HTML format instead of the user/os homedir folder.
