Add Unit testing

[proost]

setUp(): create new temp database and add one sequence with some GO, InterPro ... data

test_sequence: runs controllers and checks if the footer is in the output (which indicates the html output is correctly rendered !)

teardown(): remove database again

Note, testing profiles and networks is considerable more difficult !!

[proost]

Currently included, however, the database should exist and contain at least one record of each !

• Sequence
• Species
• Interpro
• Family
• GO

[proost]

App now has app-factory pattern which allows the unit testing to be done using a separate configuration starting with an empty database. This works, so now this needs to be expanded to include all routes

[proost]

Unit tests implemented for ALL (!) routes. Takes ~ 30 seconds to run on dummy data, not bad
