Flip drawing of negative strand PAF features in linear synteny and dotplot views

[cmdcolin]

It was seen in https://gist.github.com/cmdcolin/f9f0c1c61b7c840475c1815a7a607239 that there were a lot of "inversions" but these may be that we are not actually drawing reverse strand features right. This tries to fix that by flipping the start and end coordinates in the dotplot

We may need to make a similar confirmation for the linear synteny views

This type of change may also be needed for the linearsyntenyrenderer, e.g. for a inverted large contig seen in the after, then we expect an inversion

e.g. open this region in linear synteny view

we can also flip the top level for example

went ahead with merge...can review if needed

it is maybe interesting to note that strand only exists on "one column" of a PAF file e.g. the query can be flipped or not, and there was no handling of strand at all in the current code, so this adds that
