Rename the editor action "Revert Scene" to "Reload Saved Scene"

This option can be used to workaround various issues with stuff
not reloading properly when changes are made.
The option was renamed to clarify the fact that it actually
reloads the scene saved on the filesystem.

(cherry picked from commit 2962819d1c4e3a3835647015904e07c93ecfc370)
