refactoring package names and moving up to the refactored common jar
with updated package names (version 1.0.2 -- see commit log there for
details)

Package refactor here are roughly the same.

from com.*  -> org.*
Don't know why this has been com for so long.

from com.jacobo.gradle.plugins -> org.gradle.jacobo.plugins.
Better package convention -- tells me more looking at it

AntExecutor, DependencyResolver, and NameConverter were deleted, as they
were moved out to the common library jar (the jaxb plugin will use these
interfaces)

*.resolve -> *.resolver
*.convert -> *.converter
*.tasks -> *.task
^^ these just make more sense

All tests passing, so this refactoring was successful
common slurping library 1.0.3 used, making the AntWsImport implement a
varargs interface and using this to pass in the Episodes FileCollection
object, and use the handy `addToAntBuilder` method to add the episode
bindings that way (which is much more tidy).
