* Add macros that aren't available in SDL 2
* Comment out a variable definition for now
- For C89 compliance
* Add some comments for clarity
* Let ALSA tolerate a null new_rate
* Partial ALSA microphone support

- 0 now represents the default value

* First crack at resampling mic input
* Remove an extraneous check
- I think something distracted me when I was writing this line

* Change description of microphone sample rate in the settings
* First attempt at resampling configured mic input
* Forgot a section
* Fix some input samples being skipped
* Rename a variable for clarity
