ignore tmp under the ios directory
nestopia and snes9x-next build scripts

These get built in a tmp directory under ios. Steps:

* Clone (or pull master) repo
* build core
* move core to modules directory
main core build script, calls all the build scripts for all of the cores
removes the tmp directory
ignore all dynamic libraries in ios/modules
set the codesigning setting for Release for Distribution
ignore ios provisioning files
add build config file
build the ios app

* import the build config
* clean the build
* build the app
* codesign the emulator core dynamic libraries
* package the app into an IPA with the preferenced mobile provisioning
general overall build script
README
give the ability to disable codesigning so this build stack can hopefully be helpful to jailbreak distroing too
add an announcement to explain where they can find the app
explain where the app will be after being built
drop all the build scripts, these belong in libretro-super
script/build will do the only thing that matters, the app building and codesigning
