New Spanish translation (thanks to Raúl Morillo).
Changes to command-line launch options (see /help flag).
Last cloned window can be cloned again on start up (see Advanced options in the context menu).
Sidepanels now open in a side window instead of the main window (more reliable form drawing and simplified main window code).
Added a new settings panel (with language switching and hotkey settings).
Several bugfixes to main window behavior.
Other bugfixes and string changes.
