Delete unnecessary directories

Java directories are just not needed (not right now at least) so it's better to
delete them.
Add SBT Options for memory control

An increase of memory limits of the virtual machine is needed to accommodate
with the needs of the Linnaeus NER Tool, as the first tests with it reveals.
The settings are not correctly tweaked, they are set a bit arbitrarily, will
fix them in a future.
Add Linnaeus dictionary resources

Entity type dictionary pack "species-proxy-1.2.tar.gz" from Linnaeus website[1]
has been added to the resources directory. The project works with different
names from the ones provided in the pack, so they have been renamed.

Also, because of the big size of the dictionaries, they are compressed again
(with the fixed naming) into "linnaeus.tar.lzma". Remember to uncompress before
doing anything related to them.

Add Linnaeus NER library
