Disable reverse search, restore "?" for help popup. Map Ctrl+F to searching in CodeMirror, map Space to PageDown. Take Ctrl+A back from Vim mode for selecting all text. Disable Ctrl+O in Vim keymap since it's used by some browsers. Add explanation of key commands to help popup. '/' still starts a CodeMirror search instead of a Gerrit one. Jumping within Gerrit using the 'g' prefix is still not supported. Change-Id: Id77faa4b36add35c78edfd0d7d0611279cbe7120
