Fix issue connecting to networks with quotes

[josegonzalez]

When the entry has a quote mark, the parsing fails

echo "Test' Network:password" | xargs
xargs: unterminated quote

I do the xargs trick to remove trailing whitespace. I should check if we can use sed for this:

echo "Test' Network:password" | sed 's/^[[:blank:]]*//;s/[[:blank:]]*$//'

At worst, just ignore the xargs and assume the passwords do not have trailing whitespace.
