Added control of the node text rotation

As you suggested in #79

Thanks! I've had a quick look at this and it seems to work. Couple of comments:

• Could you please make a similar change to the clustree_overlay() function? I try to keep this in sync with clustree() as much as possible.
• I have a policy of trying to include everyone who contributes to {clustree} as an author. If you are happy to do that please add your details to the authors list in DESCRIPTION and the contributors list in README.md.

Ah sorry - was not aware of the clustree_overlay() function :-)

That does however cause a small problem as geom_label_repel() apparently does not support rotation.

Seems it would require switching to geom_text_repel() or geom_richtext(). Would that be acceptable or would you prefer it without the rotation option?

Thanks for the author offer - I do think this update is to small to qualify for that though :-)

Ah, ok. In that case don't worry about it.

Definitely not too small but if you would prefer not to that's up to you. You could just do the README list if you like.

Again thanks for the author offer but I'll pass :)

Do you have an idea when the updated version will be on CRAN?

[lazappi]

I will try to submit it in the next day or so and assuming everything passes it should be up next week sometime. I am on leave from the end of next week though so if it doesn't happen by then it will be a while longer.
