Use named parameters in command line interface

[aecio]

Currently, ache is started using a command line interface with fixed parameters like this:

ache startCrawl <data output path> <config path> <seed path> <model path> <lang detect profile path>

Command line should be modified to accept named parameters:

ache startCrawl --data-output <data output path> --config-path <config path> --seed-path <seed path> --model-path <model path> --lang-profile <lang detect profile path>

All ACHE command should accept named parameters, namely:

ache startCrawl
ache addSeeds
ache buildModel
ache startLinkStorage
ache startTargetStorage
ache startCrawlManager

It's also desirable that parameters can have a short form:
--data-output or -o
--model-path or -m
--lang-profileor -l

This feature should be implemented using a library like argparse4j (http://argparse4j.sourceforge.net) or Apache Commons CLI (https://commons.apache.org/proper/commons-cli/).

This feature is important to allow optional parameters be added in the future without breaking clients that are using the interface. For instance, ElasticSearch integration will need this feature to setup index name when ElasticSearch is used as TargetStorage backend.
