euquiq 13abb620f6 Radiosonde-vaisala-add-temp-humidity
Also added the fields "DateTime" which just shows the raw timestamp that portapack assigned the last packet received, in the format: YYYYMMDDHHMMSS ... And "Frame" which shows the packet # (or frame) for correlating with other software / verify that there are new packets being received.

Also moved a string function for returning rounded-up decimals, originally inside the whipcalc tool app, into the string_format functions library, because I used that function on TEMP and HUMIDITY values inisde the radiosonde app.

Finally, the whole UI has its widgets moved a bit, giving space for these new parameters.
