.table-row-variant mixin respects @table-bg-hover #13530

fixes #13530

Yeah, but now you're not respecting the @background parameter of the mixin, which if anything seems worse. Don't know if there's a good solution here. Maybe deprecate @table-bg-hover and use a computed color in its place?

How about to use something like this? http://stackoverflow.com/questions/18414668/set-less-variable-if-its-not-set. Hover color will be computed if @table-bg-hover is not defined.

[cvrebert]

Practically speaking, @table-bg-hover will basically always be defined (at least in Bootstrap v3).

[tivvit]

I thought about computing it's value by default. Instead of deprecating it, this wouldn't be BC break.

User can define custom color but when he doesn't default will be used.

Problem is this is not very clean, because of it is not clear there exists possibility like this, and user may be confused where this exact color appeared.
