Switch to PM loading format

This would give a few advantages:

• We would be able to reduce a bit of code for the sysmodule version, like some functions that would be handled by the CFW.
• We wouldn't have to wait 10 seconds in __appInit and hope that everything we need has been initialized
• We wouldn't be limited by the maximum file size of kips (note: this doesn't mean we would be able to use more RAM, just take up a larger portion of the SD card)
• We would be able to know where on the SD card our files are stored, if that ever matters in the future
• Nxsh could theoretically be turned on and off

I wanted to see your (@Cesura) opinion on this before I start working on it. If you think we should switch, I could probably get it done pretty quick
