Re enable 38400 baud rates

[ffissore]

Some baud rates had issues with RXTX and linux. With JSSC, they seem to work fine again. Enable them. Fixes #2296

On Linux, 14400 and 28800 are not supported. Moreover, if you try to set the speed of serial monitor to 14400 or 28800, the OS seems to accept the baud rate but the real speed on USB-CDC ACM emulated port is set to 19200 and 38400 respectively (that are the closest "standard" speeds accepted by the USB driver).

So I'm for leaving 14400 and 28800 out and keep just 38400.

Force pushed to enable 38400 only

Thanks for adding it back.

By the way would it be possible to add 250000 kbps, this speed works whatever crystal value is (4MHz, 8MHz, 16MHz) and always with 0% error. Could really be fine to have it. another way could be to let user type a custom baud rate, I know it does not works on all systems, but where it works (Windows) it could be fine to type custom baud rate instead of switching to putty every time.
Thanks
