Christian Soffke 5aa2b339d5 plugins & debug menu: apply consistent titles
Purge "Menu" or "Rockbox" from plugin menu titles
and match application names from manual.

Exception: "Main Menu" is left unchanged as the
title for the Main Menu Configuration plugin, since
it appears in Rockbox's Settings menu and therefore
should match the name of the setting.

E.g.:

"Rockbox Goban" => "Goban"
"Image Viewer Menu" => "Image Viewer"
"Viewer Menu" => "Text Viewer"
"Menu" => "Chess Clock"
"Do What?" => "Text Editor"
"Mpegplayer Menu" => "MPEG Player"
"Multiboot Settings" => "Multiboot"
"Disktidy" => "Disk Tidy"
...
