Modified startup-scripts.sh to execute mpg123 with the configured startup volume from global.conf.
The configured volume from global.conf was ignored when playing the startup sound (always played at 100%, which can be extremely loud for kids).
Now the configured volume is converted into the correct volume value for mpg123 (100% volume converts into 32768).

Play startup sound with correct startup volume

Adds an option to configure the poweroff command executed when
triggering a shutdown. Poweroff command to use is read from file
`settings/Poweroff_Command`, default `sudo poweroff`.

Scenario:
a) You are powering you Pi via an extension board, e.g. MoPi 2,
that cannot detect a regular poweroff and stays powered-on itself. Via a
customizable poweroff command you can trigger the extension board to
power off the Pi in the prefered way which finally also turns-off the
extension board.
b) You like to add some extras, e.g. LED illumination, on power off. A
customizable poweroff command allows the "user" a nice hook for whatever
stuff he likes to add before the actual power off :-)

(maint) Minor typo

update branch to 2.2rc1

if the folder.conf has SHUFFLE=ON, shuffle is executed while loading the playlist.
i don't know, why inc.settingsFolderSpecific.sh is executing shuffle again?!?!?
my opinion is, that it is not needed, because the playlist is alread shuffled.
For that reason and for testing i uncomment line 53. If everthing is ok, the IF clause could be removed completely.

added global + ignore to replace all ";" in the artist, if more than one occurs
