HOSTPORT didn't parse anything useful

Changed HOSTPORT to a simple combination of IPORHOST and POSINT. What was the old pattern supposed to do and what does =~ mean?
Added file with patterns for JUNOS 11.4 RT_FLOW log messages
Fix problem in MONTHNUM and add DATESTAMP_EVENTLOG pattern and 

Whilst trying to get Windows Event Log data into logstash I had some problems with the the timestamp format Windows uses.

Taking an example value (the TimeGenerated field provided by the eventlog input):

20131218141650.687853-000

And using:

%{YEAR}%{MONTHNUM}%{MONTHDAY}%{HOUR}%{MINUTE}%{SECOND}

I get a %{MONTHNUM} value of 1, but it should be 12. This is because the MONTHNUM pattern allows for single digit month values. I created a new pattern which removed this flexibility:

MONTHNUM2 (?:0[1-9]|1[0-2])

This, along with the pattern below works as I would expect:

DATESTAMP_EVENTLOG %{YEAR}%{MONTHNUM2}%{MONTHDAY}%{HOUR}%{MINUTE}%{SECOND}

I'm sure there's a better way of implementing this but I think this is a genuine problem.
Moved 'success' message into the begin block so it doesn't get printed if there's an error
Fixes exception when not specifying yamlmibdir

Fixes 'undefined method `empty?` for nil:NilClass exception
Add a RFC2822 compliant date pattern

The pattern is defined in RFC2822 and differs from the one defined in
RFC822:
 http://www.ietf.org/rfc/rfc2822.txt

Example:

- Add 'release.sh' to build docs + packages
- Bump version
- Update docs generator to be 'contrib'-plugin aware
Call it 'contrib plugins'

Because the 'vs' part was rather adversarial. There's nothing against
contrib plugins. It's just a new thing! :)
