Default path for inputs components

[amarinso]

If c:\DEVON is the recommended path for the devonfw distribution, it should be the default value for the path input component

[amarinso]

Devcon could try to autodetect the distribution folder at startup, looking at standard locations (like c:\DEVON)

also if people are working with different versions, a label could be shown on the initial page with the selected distribution

new commands will consider this "selected distribution" for default values
