Textra is in the wrong category

[cjblomqvist]

"textra - Vue js add-on to slide text." is in the Form -> Slider category, but it doesn't really fit there since it's not a slider library. I'm unsure where to put it so haven't made a PR, but thought it be nice to know.

@cjblomqvist textra already be on the list, if you think that it should be in another place do not hesitate to do PR
