Audacity gets a CLA

My guess that Audacity, like a lot of other desktop Open Source programs such as my MKVToolNix, has a user base whose vast majority works on Windows. On Windows it's rather common to let the user make important decisions on installation time. And due to the nature of the topic Audacity deals with, it is highly likely that the type of Windows installations Audacity is run on are single-user PCs and not multi-user systems (such as terminal servers), making the distinction between "per installation" and "per user" mostly moot.
