Keyboard shortcut for renaming layer

[Teebor9]

This would help a lot (for a lot of users I guess). Photoshop and Illustrator at lest have a mechanism, where you start to edit a layer name and you press tab the cursor jumps to the next layer name (shift tab for backwards) and highlights that. This would be amazing but using Asprite for a while using the F2 button works like a charm. (There you also jump up and down from layers with the arrow buttons. This would be neat here as well with a combo button)

@Teebor9 @Keavon can i work on this?

[Keavon]

This one is not a good first issue and I'm not prepared to offer time towards reviewing attempts at it. Please look for issues with the Good First Issue label.

Not sure if we should keep the navigation from both the flows, that is tab , shift tab and arrow keys . For now in my PR I have added them both

[Ayush2k02]

Also , some clarifications on the issue,

1. should pressing F2 get us into the editing state for layers ( defaulting to the root artboard ) or
2. after clicking on the layers / artboard should we go into editing state by pressing F2 . Like select the layer first then go into editing by clicking F2

I think 2 would make more sense.

@Keavon do you have a preference on the matter?

[Keavon]

2 is what's being requested and what makes sense, 1 does not make sense.

[Ayush2k02]

cool, my above PR already has 2 implemented :)
