* Update source installation requirements

We require Golang 1.8 since we use `net/url.PathEscape` which was not introduced until then

* Use Golang 1.8 for build and test

If we state Golang 1.8 we should test using that version as well

* Use golang 1.8 only for single build to see if everything compiles

* Change back edge also for commented out sqlite test

* Clean up spelling, grammar, perspective, whitespace, language, markup, etc.

* import docs into main repository
