Refactor access point - wip

@aldeed I’ve changed the pattern - the FS.HTTP.mount is a bit more
flexible - We could prop. have an options for { post, put, get: {
headers ? }, delete }
Should the FS.HTTP.mount also return `store`?
*Handlers could perhaps be refactored still or cleaned up*

@vsivsi check out the FS.HTTP.mount - it would allow you almost 100%
freedom (except for store selector - why I’m thinking it should perhaps
be placed in there too)
