Added version info and new MP3 Player commands 

- Added the version information to have some little hints what is done.
- Added new commands and changed two commands from the first version.
-- Intention was to get as less of commands as needed.
-- There will be possible a version with much more function and serial->read.

Command list:
- MP3TRACK
-- specify playback of a track, e.g. MP3Track 003.
- MP3PLAY        
-- Play, works as a normal play on a real MP3 Player, starts at 001.mp3 file on the selected device.
- MP3PAUSE     
-- Pause, was original designed as stop, see data sheet.
- MP3STOP       
-- Stop, it's a real stop now, in the original version it was a pause command.
- MP3VOLUME 
-- specifies the volume and means a console input as 0..100.
- MP3EQ           
-- specify the EQ(0/1/2/3/4/5), 0:Normal, 1:Pop, 2:Rock, 3:Jazz, 4:Classic, 5:Bass.
- MP3DEVICE    
-- specify playback device, USB=1, SD-Card=2, default is 2 also after reset or power down/up.

Version yyyymmdd Action Description
--------------------------------------------------------------------------------------------
1.0.0.3 20180915 added - select device for SD-Card or USB Stick, default will be SD-Card
tested - works by MP3Device 1 = USB STick, or MP3Device 2 = SD-Card
- after power and/or reset the SD-Card(2) is the default device
---
1.0.0.2 20180912 added - again some if-commands to switch() because of new commands
---
1.0.0.1 20180911 added - command eq (equalizer 0..5)
tested - works in console with MP3EQ 1, the value can be 0..5
added - USB device selection via command in console
tested - looks like it is working
erased - code for USB device about some errors, will be added in a next release
---
1.0.0.1 20180910 changed - command real MP3Stop in place of pause/stop used in the original version
changed - the command MP3Play e.g. 001 to MP3Track e.g. 001,
added - new normal command MP3Play and MP3Pause
---
1.0.0.0 20180907 merged - by arendst
changed - the driver name from xdrv_91_mp3.ino to xdrv_14_mp3.ino
---
0.9.0.3 20180906 request - Pull Request
changed - if-commands to switch() for faster response
---
0.9.0.2 20180906 cleaned - source code for faster reading
---
0.9.0.1 20180905 added - #include <TasmotaSerial.h> because compiler error (Arduino IDE v1.8.5)
---
0.9.0.0 20180901 started - further development by mike2nl - https://github.com/mike2nl/Sonoff-Tasmota
base - code base from gemu2015 ;-) - https://github.com/gemu2015/Sonoff-Tasmota
