toolbar: Add and fix tooltips according to HIG

currently there are no tooltips in the path bar and some tooltips don't match the guidelines

According to the HIG: back button shouldn't be "Go Back" forward is the same the pathbar needs tooltips the menu buttons both need tooltips view switching should be "List view""Grid view"

this commit adds tooltips to each button in the path-bar and each menu button gets the an appropriate tooltip the text is fixed in pre-existing tooltips without changing the code

Closes GitLab issue #2349 (closed)
