Godot: Regression: We can't rename actions in InputMap

[henriiquecampos]

Godot version:
3.2.alpha.official

OS/device including version:
Solus 4.0 Gnome 3.34.1

Issue description:
In 3.1 when we clicked the action name in the Project->Project Settings->Input Map we were able to edit the name of the action, as it seems it is not possible to do this anymore

Ps: As it seems this regression seems to happen very often in Godot (#517, #27113...)

Steps to reproduce:

1. Go to Project->Project Settings->Input Map
2. Try to click on an action
3. It doesn't allow you to edit its name

Minimal reproduction project:
Any default project

Note that it's normal that you can't rename default actions (ui_*).

But indeed custom actions used to be renamable.

Working on Master. Click the name of the action and press Space.

But yes, it's weird that the text input opens on the corner and is so tiny. It should replace the label while it's editing.

Also, pressing Space is not very intuitive. I'd expect a double-click to work.

Pressing Enter also works, which is the standard for MacOS. F2 doesn't.

IINM double click used to work for that.

On 3.1.1 you just needed a single click

I have checked this issue in v3.2.alpha.custom_build.9fcd38fc7 (which is basically built from master). I see that we are unable to change the name for default actions (ui_*). But for custom actions I am able to rename the actions.

Tested on : Ubuntu 18.04.3 LTS
Suggestion: I guess a double-click to change the name should be better as this operation would feel much more similar (as with other applications), and correspondingly more use-friendly.
I am Open to suggestions

I am on it, the problem is already solved. I'll push the PR ASAP.
