* [Toold] Add editor snippets to help new developers.
We do have a few tings that we have to do manually yet it is repetitive,
I am adding the vscode (soon to come vim) configuration files to provide
useful snippets when working with the bindings.
The syntax of the snippets present is very simple, there are just two
things to understand in these new ones:
1 Tab complitions: $1, $2 etc.. are the tab complitions that the user
can provide. This allows the user to navigate and the snippets engine
will replace all the complitions with the provided text.
2 Options: We can provide options for tab complitions, for example for
the PlatformName, which is a known value. The syntax to do so is
{$1|one,two,three|} where:
* `$1`: is the tab completion.
* `|one,two,three|`: are the options.
