Unaligned logo when you edit @grid-float-breakpoint

overrides.less file doesn't respect the variable @grid-float-breakpoint, that lets you define the point at wich the navbar becomes uncollapsed (default is @screen-sm-min).

It results in a minor un-alignment of the logo (margin left).

In overrides.less line 175:
@media @tablet {

has to be replaced for:
@media (min-width: @grid-float-breakpoint) {
