Implement morphological data imports from the server

[nataliashitova]

We need to implement morphological data imports from the server to be able to process

Researcher side

• Add morphology research to the list of default researches in the researcher
• Add an array of morphology-specific imports to the researcher
• Add method that requires research data (language-specific morphology files): getReserchData( researchName )

Research side

• The function should call the getResearchData (see Researcher side) and if no research data available build structure without morphology.

Morphology data side

• Recode regexes into strings so that they can be stored as a json file.
