Issue 1071 (GDS2Text format options issues) (#1085)

* Fixed first issue (UI problem with GDS2Text options)

* Fixed problem with 'save' when the file extension does not indicate one of the known formats

In this case, and when plain 'save' is used, the original format is delivered.
The session files also store the original format now.
The statistics page will now indicate the format of the file that was loaded.
