Excluding commons-beanutils-core from commons-collections dependency

[akki-pesit]

Solution for issue: Exclude the wrong library #201

My initial investigation of the dependency tree shows that commons-configuration library used commons-beanutils-core:

[INFO] +- commons-configuration:commons-configuration:jar:1.6:compile
[INFO] |  +- commons-lang:commons-lang:jar:2.4:compile
[INFO] |  +- commons-logging:commons-logging:jar:1.1.1:compile
[INFO] |  +- commons-digester:commons-digester:jar:1.8:compile
[INFO] |  \- commons-beanutils:commons-beanutils-core:jar:1.8.0:compile

Hence excluding commons-beanutils-core from the same.
