Add default filename for exports

Browse Source 
When exporting a single file, the filename defaults to the current FCStd
name plus a dash and the name of the object. If multiple objects are
selected, the default is the basename of the FCStd file. No extension is
added. This behavior is controllable via two hidden preferences,
BaseApp/Preferences/General/ExportDefaultFilenameSingle
BaseApp/Preferences/General/ExportDefaultFilenameMultiple

_Allow regeneration of default on new exports_

If an export has been done and it used the default filename, on the next
export regenerate the filename (potentially updating the selected object
name in that filename) instead of just defaulting to the last name.

_Search for extension in chosen filter first_

Originally the file dialog simply searched for the first available extension
in the overall filter list. This commit modifies it to first check the
selected extension, and only if that is empty to search the full filter
list. This section of code only runs if a default filename is set but
does not have an extension ("suffix" in Qt's terms).
