OveroSync: When first connected, send all the settings

Previously the overo logs had no settings which was quite annoying.  This
will likely drop some of the settings so needs further work, but should be
an improvement.
OveroSync: Use linux case instead of camel case for function names

Keeping camel case for the task start and init for consistency
with the rest of the application.
Overo logging: Send the settings every thirty seconds

Since the FC doesn't know when logging starts and and the overo doesn't
log all settings when logging starts (and we shouldn't assume it will
because that would require the overo to always be synced with the UAVO
set), this just sends them all every thirty seconds.
