WayVR display names converted to lowercase

[SamWilsn]

Introduced in 3c79260, it looks like the keys in the displays member of WayVRConfig get converted to lowercase. Possibly not a bug, but if this is intended behavior, the config file should be updated.

I have been wondering why the apps from the catalog failed to launch with for example action_app_click failed: Cannot find display named 'Disp2'.
Now, I don't use this feature currently, and had just the default wayvr.yaml, and did not have the time nor interest to dive deeper to find what broke, but had it at the back of my mind.

Now, with the information that displays are converted to lowercase, and as linked above the default config has Displays names with upper cases, that are then also used with the same spelling (logically) for the target_display.
But it seems target_display values do not get "normalized", so running as is gives you an error, but you can get it to work by changing the target_display to lower case manually.

But as it stands the default config (and old user configs based on it) are borked, and the error message is a complete red herring in this case, so I say this is a bug till both behave the same (lowercase both is probably the best solution).
