Removing mod_test (moved to simplepush_test repo)
Modified to point to new testing repo
Adding simplepush_test submodule
Heka message cleanup.

* Format update messages for simpler heka parsing.
Add the number of active connections to the status

* This reads the number of known, active connections. These only include
  clients that have sent a "hello". Need to add a auto-kick to boot
  clients that don't send a hello after some period of time.
Add socket timeout on pre-hello idle.

By default, don't time out (useful for development).
* removed "radical" from development statement for README.md
* Added sample heka toml conf file
* Moved ClientPing no-op wrapper func higher in file so it's more
  visible.
Change status message to be JSON
Attempt to resolve socket timeout issues

* reduce the amount of memcache clients to one, let it sort them out.
Single memcache handler

* formatting
Issue #41: Try fix memcache session handle overrun

* Added current_host param to pushEndpoint config entry
* Added "/realstatus/" that does a deeper check and provides more info
* Added rtilder's memcache patch for LRU handles
* Added socket max limit for server (defaults to 1000)
* Moved GenUUID to utils package
* Made memcache timeouts non fatal to app.
* Added memcache status checker
* Memcache handles are now func local
  (Global handle was keeping reapable handles alive.)
* Added file:line to heka error logger.
Starting multi storage support

* moved util and storage to aliased imports
* fixed int type errors around max_connections
* moved client counter to mutex locked function because paranoid
* fix to logger to not add fields to outbound message.
* Added simple redirect constructs for future dev.
Removed duplicate field def
Setting a GOROOT isn't needed, but GOPATH is.
Refactor memcache client creation to use the pool.
Use gomc library (not stable)

* Getting CONNECTION ERROR after small number of connections.
go fmt
Initialize the clients in the code where the clients live.
No logical reason for an unlock here.
Refactor to use a return channel for clearer semantics.
Add a buffer to the Ccmd so that the worker can directly call ServerCommand without endless blocking.
