qt: Add Montserrat (picked in Dash Style Guide) as application font

Includes the following methods
 - GUIUtil::loadFonts to load the fonts into the application's font
database
 - GUIUtil::setApplicationFont to set the application font depending on
the active theme
 - GUIUtil::setFont to set a specific font variation for a vector of widgets (Montserrat for dash themes, system default for traditional theme).
 - GUIUtil::getFont to get a specific montserrat variation as QFont (Montserrat for dash themes, system default for traditional theme).
 - GUIUtil::getFontWeightNormal to get the font weight to be used for normal text
 - GUIUtil::getFontWeightBold to get the font weight to be used for
bolder text
 - GUIUtil::getFontNormal to get the default normal weighted QFont
 - GUIUtil::getFontBold to get the default bold weighted QFont

There is a Qt bug on macOS (at least with macOS 10.15.4 and Qt 5.7.1)
which leads to not mapping the font weights correctly to the different
font types so that they can be selected by the appropriate methods to
set the font weight. As result there is now way to properly select the
different font styles from stylesheet or with QFont::setWeight() for the
font Montserrat. There are only two different weights selectable over
the full range of possible weight values. One very bold one and the
"ExtraLight" version. As workaround its possible to select the fonts by
using the font style string (QFont::setStyleName) as the Montserrat font becomes loaded as one
family with one "font style" for each font file. The font wrapper added
by this commit are taking care of this behaviour for all operating
systems so there should be no other usage of QFont outside of GUIUtil and no more font changes in stylesheets.
