docs: restructuring/improvements

[bochinchero]

Documentation is currently spread across the readmes, docs/wiki and specs in the repo. For new users, particularly those who are less technical, it may be a bit difficultt to locate certain bits of key information.

I'm creating this issue to propose and discuss restructuring the docs/wiki to make documentation easier to navigate and follow. Once the overall structure/direction is kind of settled, I'd like to turn this into a task list so it can be worked through and track progress.

IMHO the structure/format used by dcrdocs to cover Decred and Decrediton is a pretty good place to start - below is a first pass on how I think something similar would look like for dcrdex:

EDIT: Left this for a few weeks since I know folks are quite busy, I'm assuming the proposed structure is good for a first pass and have started a draft PR that will probably cover a good portion of this work, updating the below to a task list.
