Subject: hard coded height value in manoj-dark theme causes problems when increasing default-face-height

If one uses fido-vertical-mode and temporarily increases the
default-font-hight by using the function (set-face-attribute 'default
nil :height 180) the completions will not scale properly. I've looked
into the source code for the theme and it shows that the
completions-common-part variable is hardcoded to a value of 81. It
should be changed to a relative value (something like 0.8) so that it
scales properly.
