* Reactlog shortcut was broken due to reactlog.js not being included in
the gruntfile
* Reactlog has always shown every reactive event since the beginning of
the process (or at least since options(shiny.reactlog=TRUE)). This
commit makes it so Ctrl+F3 invocation only shows reactives that either
belong to no session (e.g. observers and reactives declared at the top
of server.R), or belong to this session.
This has been broken since we switched to jsonlite. Reactives
don't highlight because their srcref is in an S3(?) class that
jsonlite doesn't recognize, whereas RJSONIO would treat it as
a numeric vector.
This reverts commits deffc90, ab4dc64, and 0755579, returning to RJSONIO.
The purpose of this is to prepare for a maintenance release for 0.11
without the switch to jsonlite, to reduce the risk of new bugs.
