Workflow bugs, themefixes and refactored location display to a js class

- Simple workflow action couldn't re-display its values from the rule edit dialog
- New repo doclienst webscript: slingshot/documentlibrary/location.get for resolving a file/folder's repo- (& site-) locations    
- New class Alfresco.Location that takes a nodeRef and figures out how it shall be displayed regardin to where user is browsing and if folder is in a site or not
- Run in background option in rule edit now in right column to save vertical space
- The "When" rule config section's select drop down is now wider so its fully readable
- Flash upload now looks ok in all themes
- Rules list "Inherited from"-link now working correctly
- alfresco.js' combinePaths() now handles null values
