Various fixes and improvements

[RobertBColton]

• Addresses selection issues with drag and drop. Can now drag and drop from one action list to another again. The problem was that we needed to check if indices is not-null in import to make sure we are importing from the same list we are exporting from. Corrects Action List Selection #170
• Prevents the user from being able to add a code action to a list when there is no action container, which is how the LibActionButtons handle it as well, fully correcting Action List Lost Changes #157
• Removed files previously committed by mistake and adds them to gitignore including *.log files which are JVM crash logs.
• Adds a check to see if audio clips are open before closing the on the sound frame. This is to fix a Linux issue where the pulse audio implementation in OpenJDK does not like you calling stop if the clip was never actually opened before.
• Fixes a mistake in the action list model where one of the add() methods stored two undo's. Lead to an exception just adding a single action and undoing twice.
• Removes swinglayout-lgm.jar from class-path in the manifest because we no longer support Java 5.
• Restores the status bar on the background frame to the way the others are done until we create a real status bar layout.
• Uses the new ICO file created by @JoshDreamland without any aliasing.
