Load postloader data into memory

[GoogleCodeExporter]

I suggest to make postloader and it's data (theme, settings, etc) load into 
memory after launchup.

Reason: Whenever someone takes out the SD card, postloader freezes, because it 
no longer has access to the theme files, settings, etc.

The device containing /ploader folder cannot be removed. Probably the main 
reason for the hang are the covers, as almost of the other thing are already in 
memory.

The only thing I can do is to check if the card is removed and ask the user to 
insert it again.

Well, i replicated this issue again but now removiing all covers from covers 
and covers.emu, then removing the sd, It still froze.

After, i reinput the SD card into the wii, the hand did move a few cm, but then 
it refroze again fast, same is if i did not remove the covers.

Btw, if i remove the SD inside usbloader-gx, i can still move around or change 
view without problems, including having the covers loaded last time+games, 
except if i try view homebrew or any events where it needs the sd.

Even when i take out the USB device, it still does not mallfunction), though it 
does not reload its data of games availble :/.

Postloader still freezes in beta 4.b33 if you try to take the sd out at 
sections that involve the SD to be input, such as emulators and 
homebrew(strangely also channels :?).

If you try this at sections that involve USB access, it will not freeze, though 
it will freeze if you try to go over to any different sections from the upper 
toolbar.

I suggest, that in the event someoene takes out the SD, a warning should be 
given to put back the SD device, cancelling out most to all actions+darkening 
the background perhaps.

When someone puts back the SD device, all actions are allowed again, same 
applies to the USB, may it store its configs instead.

There is one problem still, if i try to put the SD back, postloader won't 
return to what it should do, as if it does not reread the device and forgot it, 
though it does not freeze as if it couldn't load the files :L.
