update changelog

## Link to GitHub Issue, if one exists
#345 

## Description of change
On launch of spice.exe / spice64.exe, call `regsvr32` on known codecs in
the `com` directory.

Add an option to skip this (`-ddrnocodec`) as a chicken bit.

## Testing
Tested 32 and 64 bit DDR.

 Rules for filing a new issue or adding comments to existing issues in the tracker:
 
+* Low effort submissions will be simply deleted, and repeated attempts will get you banned.
 * Check the [known issues](https://github.com/spice2x/spice2x.github.io/wiki/Known-issues) page first before reporting a new issue. If you have some new information or workarounds for a known issue, you can file a documentation bug as well.
