Remove trailing spaces from subunit texts

Some texts have a trailing space in the end. This is
unintentional. These trailing spaces should be removed since
they cause a last second surprise to the user while finishing a
subunit.
Use OnePixel logging instead of 1x1 logging

OnePixel logging allows arbitrary number of key value pairs to
be passed to the logging function. An example of OnePixel log:

    OnePixel.log('name', 'QuickQWERTY', 'version', Version.NUMBER)

Switch to OnePixel logging for QuickQWERTY.
