Small Updates

Several updates for improving the UX

This should be a context menu option "Make As Root Directory" for directories and not a double click option. It happens to often randomly when opening/hiding the tree.

When a file or directory is created it closes all directories, that's weird. It's maybe a refresh bug.

Files need a menu entry to open them in other than the connected editor. For example a "index.page"  should have:
Open  > 
   Default (Page Editor)
   Code Editor

While a "mc-joe.rojo" should have:

Open > 

    Default (Rojo Settings)

    Rojo Chat

Currently the toolbar on the left takes a lot of space vertically. Remvoe that HTML element and and the tools to its normal toolbar on top. Make a bit space to the normal editing options (Pin/Undo/Save) and than put block selector and style selectors next to it.
