in the future we can hopefully migrate nicely over to the distro provided package.
change emulation station depends to look if sdl is installed, and install from binary packages if not.
the binary package for sdl2 is hidden from the menu now - it can be considered a core dependency which we can make packages rely on as needed.
values at once, we now have a iniConfig function that sets up the delimiter type (such as "=" or " = "), the value quote
character (often "" nothing or "\"" a single quote) and the filename. you can then just call "iniSet" or "iniUnset" with two parameters
for key and value. A third parameter can be used in case you wish to use the current ini settings but on a different file. We should now easily
be able to handle any key/value configs whilst keeping the code simple/compact
note the startup script set up was moved to the configure part - since with the binary shipped version, we will need to call configure
to recreate it (install won't work since install now installs from source location to binary location)
