Allow state change of "Get" button when package is queued

[brennanleblanc0]

In the current beta (1.2b1), when the get button is selected to install a package, it’s state does not change and remains at “Get”.

What would solve this is to change "Get" to "Queued" (or something along the lines) when the package is selected. This would help avoid confusion when you’re selecting many packages at a time.
