Issue description:
Using # to comment out a line under the autoload header in the configuration file causes GZDoom to remove the entry (upon launch?)
Reproduction steps:
* Add an entry under any Autoload section in the .ini file
* Comment out the entry using a # mark
* Launch the appropriate game
* Exit and check the configuration file again
* Note that the commented line has been deleted entirely
Suggested fix:
* Do not delete commented lines
Why is this an issue:
It's convenient to use comments to temporarily disable items in autoload to test when you have a problem. Frankly I did not expect the engine to delete them and was a little frustrated when I lost the contents of my autoload, lol.
