Resources in Maintenance mode are showed as Free

[dahorak]

After recent change, when Enter Maintenance mode functionality was moved to sub-menu Actions, it is quite hidden the fact, that some resource is in Maintenance mode.
See on the following picture, the three resources in the pink rectangle. The only clue is the wrench and screwdriver icon on the Actions button, which is not too much visible.

Would it be possible to reflect the Maintenance mode in the Status column? For example like this:

• FREE
• LOCKED
• MAINTENANCE
• LOCKED - MAINTENANCE

When the resource is both locked and in maintenance mode, I think it make sense to reflect both states, but when it is not locked but in maintenance, I think the correct description is only maintenance.
