Rename the Groupname in Pages and sections

Hello,

you have to differentiate between views, pages and groups.

A page can contain multiple views (for example to zoom to specific parts of a larger page). Each page always has at least one "main" view that spans the whole width and height of the page. Unfortunately in the current version a page can't be renamed. Views and groups however can be renamed. 

We looked into renaming the page when the main view is renamed, however this turned out more difficult than it seemed. We plan to make pages renameable with the next major release of QuickHMI later this year.
