JBoss - Update invoker servlets

* src/platform/jboss/deployers/ejbinvokerservlet.py
  src/platform/jboss/deployers/jmxinvokerservlet.py
  -- As stated in issue #21, we weren't prompting the user if they
  provided a war file, and instead bailing out.  We now prompt them
  to default to cmd.jsp before bailing out
Added error handling for invokerservlet authentication failure
Merge branch 'dev' of https://github.com/hatRiot/clusterd into dev
Merge pull request #22 from breenmachine/dev

Added error handling for authentication failure on JBoss InvokerServlet's
WebLogic - Support for invoke

* src/module/invoke_payload.py
  -- Since moving over to the jsp payload, we can now invoke
  on WebLogic.  This wasn't previously possible due to some
  unsupported functions in WebLogic, but this new jsp payload
  works flawlessly.
ColdFusion - Fixed a bug in task scheduler

* src/platform/coldfusion/deployers/schedule_job.py
  -- Fixed a bug that came about when adding the external port
  handler.  The port and IP were switched around!
  -- Added a test for the run_task to correctly fail out
Fixed requirements file
README refresh, added new payload flag

* README.md
  -- Refreshed to version 0.3
* src/core/deployer.py
  src/core/parse_cmd.py
  -- Added the --rand-payload flag, which will randomize the deploying
  file with a 5 character name.  This can help if you have a payload
  file that you don't want deployed with any suspicious context, such
  as "shell" or "reverse_meterpreter"
* src/module/invoke_payload.py
  -- When invoking payloads, only print the context, not the full path
* src/platform/railo/authenticate.py
  -- Display an error on unsupported auth interfaces
Merge branch 'dev' of https://github.com/hatRiot/clusterd into dev
JBoss - Added support for WildFly 8.1
JBoss - Fixed missing import in the JBossStatus fingerprint
Catch fingerprint exceptions

* README.md
  -- Updated to reflect JBoss 8.1 update
* src/core/fingerprint.py
  -- Initially I wanted to handle all exceptions in fingerprints, but
  that doesnt appear to be very feasible.  We now catch and log all exceptions
  not caught by the fingerprint, as opposed to crashing horribly.
JBoss - Added 7.x/8.x undeployer support
Version bump for merge
