[MOBY-dev] jmoby CentralImpl is updated

[Edward Kawas]

Hi,

CentralImpl has been updated to reflect the newest mobycentral
endpoint/namespace.

2 methods were created: getDefaultURI/getDefaultURL that query
http://biomoby.org/mobycentral iff the system property 'moby.check.default'
exists and is set to true.

***IMPORTANT***
Also, note that a new dependency 'commons-codec' was needed so make sure to
do an 'ant gather' | './build-dev.sh gather' before using the new code.
