feat(unitproc):Add script to load dconf settings from file

Script is `bkdconfwf` (baltakatei dconf write file). Currently, the
command:

    bkdconfwf gnome-terminal.conf

is currently functionally the same as:

    dconf load / < gnome-terminal.conf

where `gnome-terminal.conf` is a snippet taken from:

    dconf dump / > dconf_backup

formatted like:

    [org/gnome/terminal/legacy/keybindings]
    prev-tab='<Primary><Shift>b'
    find='disabled'
    move-tab-right='<Shift><Alt>f'
    find-previous='disabled'
    next-tab='<Primary><Shift>f'
    find-next='disabled'
    move-tab-left='<Shift><Alt>b'

However, because processes each <key> & <value> string individually,
future custom behavior may be programmed into the script. For example,
it may be desireable in the future to combine the following keys:

    key="'['one']'"

    key="'['two']'"

into:

    key="'['one' 'two']'"

.
