* clean up plugins GoDoc: - eliminate plugin.NewBlankContext() as unnecessary - export ValidIdRegex as a string vs. the less readable var - add/update various documentation strings - hide everything by default, except where used by client plugins or the mattermost-server. The exception to this rule are the `*(Args|Returns)` structs which must be public for go-plugin, but are now prefixed with `Z_` with a warning not to use. - include a top-level example to get plugin authors started This is not a breaking change for existing plugins compiled against plugins-v2. * remove commented out ServeHTTPResponseWriter * update examples to match developer docs * add missing plugin/doc.go license header
