Icon Request: Toilet

[benjavicente]

Related to #359. The problem with the current bathroom icons, is that they don't convey the minimal elements that are usually considered a bathroom: a Toilet and a Sink. A shower (bathroom icon) and the Woman-Man symbol (wc icon) don't fit well in all contexts, like with small guest bathrooms that don't have a shower.

The wash icon could be considered a Sink, but there's no icon for a Toilet.

Thanks in advance.
