Suggestion on UI/UX for better control on tools and simpler access to tools

[hadimansouri]

I suggest adding the following buttons at the end of each item in the tree view of the page editor:

1. edit style: if the user clicks it we can show style editor (either by opening it in a separate dialog or activate it in the side-nav).
2. edit code: if the user clicks it we can show code editor (either by opening it in a separate dialog or activate it in the side-nav).
3. edit text (only for textbase elements such as h1, a and so on): if the user clicks it we can show text editor (either by opening it in a separate dialog or activate it in the side-nav).
