- mainly just some various code cleanups
- added 'Always show main icons' option page 14 of main settings. this prevents the main screen icons from hiding.
- fixed a minor issue when changing a plugins rom dir but then exiting the source menu via B button without selecting a source, it wouldn't reload the current coverflow but now it does.
- now when you have only the front cover image wiiflow will use that platform's custom blank cover image for the spine and back of the cover.
- made source menu setup menu's more noticable when you switch from select a source to selecting a plugin and back. before it was hard to tell you had moved to a new menu cause they look nearly identical.
- added wiiflow/covers/homebrew_small folder so when using homebrew smallbox mode you can use your own custom covers instead of the apps icon.png
- fixed music resample to 48k option on main settings to not crash wiiflow if only one song file in wiiflow music folder.
- fixed displaying music title when you only have one music file in wiiflow music folder.
- fixed saving and loading enabled plugins upon exit and startup. This stops the "no plugins selected" message upon returning to wiiflow when you previously used the Select Plugin Menu.
- fixed custom backgrounds after using the Select Plugin Menu.
- fixed the Source Menu to display source buttons properly when switching tiers or pages.
- fixed refreshing Source Menu buttons after using the options menu to hide them.
