(dev/ephemeral deployment) remove unneeded line from post-create script used for aws targeted deployments

a tool for looking at browserid stuff in localStorage sqlite databases on Firefox, Chrome and Safari

process.env converts all values set into strings,
so its better to just not set it.

- Windows doesn't have signals, so process.on("SIGINT") throws
- changing process.env.PATH is a bad idea

making this script cross-platform

disable debug language in our dev env for now.  it was never working right, and was relying on obsolete .json files.  Now that those are gone (see PR #1918), we can see that things were broken.  See issue #1970 to track the fix

make sure our example RP and primary point to the right location, this was broken way back when we introduced router

fix debugging locale - allow the template to not specify a charset properly - and don't msgmerge db_LB, it's regenereated afresh each time

run_locally should work well with CONFIG_FILES (not overwrite it so you can pass in extra config on the cmd line

The `static` process has been added to handle cachable resources and views, so
code relevant to serving those resources has been removed from `browserid`.

The `router` heartbeat now depends on both `browserid` and `static` processes being ok.
`router` now forwards wsapi writes to `dbwriter`, reads to `browserid`, and errors on unkown
or internal wsapi requests. The wsapi setup for `browserid` no longer handles forwards, though
some wsapi operations may trigger a forward to `dbwriter`.
