Make the difference between _Apply_ and _Save_ implicit

[losandes]

Some settings support an Apply feature so changes are not persisted beyond the current session (i.e. changes to Siz & Pos can be applied without saving). As a non-power user of cmder, because this button is a fair distance from the Save Settings button, it's not implicit that the changes are not going to persist beyond the current session. Following are a few ways you could make this more obvious:

1. Indicate that the changes are for this session only (i.e. Apply for this session instead of Apply)
2. Make Apply a universal feature, and put it next to the Save Settings button. This might make the difference between Apply and Save more implicit.
3. When user exits the Settings dialog without saving their settings, confirm that they don't wish to persist the settings beyond this session
