Generate fiji url links and process them: in progress

[mzouink]

Added generate url wrapper
and process url service:

TODO :
[] Handler in : src/main/java/bdv/tools/links/BDVLinkHandlerPlugin.java is not done
[] BDVLinkHandlerPlugin needs new fiji, so we need to make it as option that works only if LinkHandler is available

[mzouink]

i removed the link handling, it will be a serparate project but i think we can have link generation here
only thing missing is to agree on the link :

bigdataviewer-core/src/main/java/bdv/tools/links/Links.java

Line 47 in 5b72d6a

final static String BASE_URL = "fiji://bdv?";
