[Networking] Change wpa-conf to wpa-roam
[Networking] More network script changes

Only kill the necessary dhclient processes rather than all of them.

Kill ifplugd for eth0 and wlan0.  Set "auto eth0" and "allow-hotplug
wlan0" since there is no ifplugd for these interfaces.

Use a virtual FPP-wlan0 interface for wlan0 so we can support using
a static IP on wlan0.
[Help] Add a line break to GPIO help
[License] Add license file indicating fppconvert is GPL v3

The rest of FPP is GPL v2, but fppconvert uses xLights source code
so that makes fppconvert GPL v3.
[License] Add a license file for external components and their URLs
[Testing] Add a Channel and Sequence test screen to the UI.
[Debugging] Update debug log to show proper channel numbers
[Media] Add mediaOffset setting to allow adjusting sync offset
[Media] Add oggPlayer and mp3Player hidden settings

These allow overriding the use of /usr/bin/mpg123 and /usr/bin/ogg123
directly to allow testing outputs other than ALSA.
[Debugging] Remove sequence debugging from developer page

This is on the testing.php page now, so it doesn't need to be
duplicated on developer.php.
