Added GenericXMLDataBinding and EchoProcess
Bugfixes
Replaced use of SimpleBufferAlgorithm with...

... EchoProcess.
Started using EchoProcess also for ExecutePostIT
Increased maxOccurs of inputs
Changed some more tests to use EchoProcess
The functionality to create a GTVectorDatabinding

out of a shapefile was moved from GenericFileData to a new class
GenericFileDataWithGT. Test processes that used the old GenericFileData
were moved from algorithm-geotools to algorithm-impl.
merged branch 'echo-process-tests'
Switched more tests to GeoTools free processes

Also added a base64 encoded tiff as sample input data.
Integration tests can now be executed without...

... the with-geotools profile. WPS-T,- Axis- and FeedServlet had to be
removed from the web.xml.
Update .travis.yml

enabled integration tests for travis CI
Cleaned up
Accelerated tests by decreasing the wait-interval

for asynch tests from 10 to 3 seconds. There are still 4 attempts made
to get the result, i.e. overall the process has around 12 seconds to
finish. On my local machine 2 attempts were needed at maximum.
Execute POST Test now use only local resources
Execute GET tests now use only local resources
Merge pull request #73 from bpross-52n/genericfiledata-refactor
