Update nFeed API version

We need to update the version of the nFeed API from the version 0.0.2 to the last version, 0.1.0

This must be done on the POM of the CORE project of Xporter.

Also, we must make a compatibility matrix between Xporter versions and nFeed versions.

 An unconfirmed matrix is this:

All nFeed versions up to 5.11.4 use the nFeed API JAR version 0.0.2 and can be used with Xporter 5.3.2 and below.

All nFeed versions beginning at 5.12 use the nFeed API JAR version 0.1.0 and Xporter 5.3.3 will work with this version. All previous versions of nFeed will not work with Xporter 5.3.3 and above.
