frontend: enable protocol autodetection by default

Browse Source 
It seems to work rather well after some extended testing. Also clean
up and update the protocol documentation while at it.

### Protocols
STC MCUs use a variety of related but incompatible protocols for the
BSL. The protocol can be specified with the ```-P``` flag. Optionally,
experimental protocol autodetection can be used. The mapping between
protocols and MCU series is as follows:
BSL. The protocol can be specified with the ```-P``` flag. By default
UART protocol autodetection is used. The mapping between protocols
and MCU series is as follows:
* ```stc89``` STC 89/90 series
* ```stc12a``` STC12Cx052AD and possibly others
* ```stc12b``` STC12x52xx series, STC12x56xx series and possibly others
* ```stc12``` Most STC10/11/12 series (default)
* ```stc89``` STC89/90 series
* ```stc12a``` STC12x052 series and possibly others
* ```stc12b``` STC12x52 series, STC12x56 series and possibly others
* ```stc12``` Most STC10/11/12 series
* ```stc15a``` STC15x104E and STC15x204E(A) series
* ```stc15``` Most STC15 series
* ```usb15``` USB support on STC15W4 series
* ```auto``` Automatic detection of UART based protocols
* ```auto``` Automatic detection of UART based protocols (default)
The text files in the doc/ subdirectory provide an overview over
the reverse engineered protocols used by the BSLs. For more details,
