Clean less files

[xf-]

• replace tabs with spaces
• remove unit from 0 values
• add empty lines between selectors
• split important with a space in all occurrences
• combine margin: 0 with margin-top, -bottom, left, right to one line.

(And maybe add a linter afterwards, new code is more unified, easier to understand)

I think some of the empty lines were removed in a recent PR by @lafriks

@techknowlogick this is most common usage. easy to find a selector.

No empty lines if no selector/ attribute is in between. eg.

  }
}

i try to get an linter into lessc - it has an plugin (i mostly use sass and a gulp build pipeline). Source map is the next goal. Is only loaded if Development console is open

Btw:
Current, but single selector per line is a nice rule

footer {
	.ui.container .left, .ui.container .right {
		@media only screen and (max-width: 880px) {
			display: block;
			text-align: center;
			float: none;
		}
	}
}

Single line (and max-depth to avoid very large selectors):

footer {
    .ui {
        &.container {
            .left,
            .right {
                @media only screen and (max-width: 880px) {
                    display: block;
                    text-align: center;
                    float: none;
                }
            }
        }
    }
}

Sounds good. If you could get that linter in here as well that'd be awesome.

Thanks for all your contributions recently.

[lafriks]

@techknowlogick nope, I also added some newlines :) But only in one file that I was changing

[techknowlogick]

@lafriks ah ok. I just remembered something about empty lines. Thanks for clarification.
