Adapt cnncreator template

See merge request !5

Added indented block in all layer templates due to changes made in CNNCreator.ftl in order to avoid a python error

Bugfix: ${input} in convolution template (case: input same as data input) should not be a reference anymore due to the new version of the add_input function.
Test must be made with Blob "data" always due to the new version of the add_input function.

-Deleted dummy data and label
-Added correct function add_input so lmdb data sets can be read as input for the networks.
-Save the deployment model instead of the test model to avoid including the lmdb reader.
-Adapted functions so they can take the data and label values from the function add_input.
-Included training parameters EPOCHS and BATCH_SIZE; they do not apply for testing.
-Included a proper image test.
-Improved print messages.
