Upgrading commons-codec to 1.13 after sonatype-2012-0050 vulnerability

[bahui80]

Updating library needed to sort out vulnerability sonatype-2012-0050

Description:

The Apache commons-codec package contains an Improper Input Validation vulnerability. 
The decode() method in the Base32, Base64, and BCodec classes fails to reject malformed
Base32 and Base64 encoded strings and consequently decodes them into arbitrary values. 
A remote attacker can leverage this vulnerability to potentially tunnel additional
information via seemingly legitimate Base32 or Base64 encoded strings.

@bahui80 We have already upgraded master (5.0) to Commons Codec 1.13 but we cannot upgrade the 4.5.x branch due to version 1.13 incompatibility with Java 1.6 required by HttpClient 4.5.

@ok2c i wasn't aware of the requisite of Java 1.6 for HttpClient. Thanks anyway!
