[XCL] PDA Girls 1.1.0

Buy a PDA! Totally not a BlackBerry!

The PDA Girls file just adds the ability to buy and open the PDA, but doesn't add any apps for it. Notes App Girls adds a notes app to display your notes in the right sidebar. A girl writing in her notes app is her magical power.

The idea is that if people find the PDA useful, adding apps for it is pretty easy. The `pda_button` passage tag lets you add your apps with minimal pain, and you can use Notes App Girls as inspiration for how.
