Update 20170422



BIC Library:

* Moved filtering function to server: on changes after 0.5 seconds server is requested for details based on filter. Only 100 results are return, unless you reset filter, otherwise you get all active BICs

- Removed "Inactive participants" checkbox, since it was initially used only for performance improvement, when calculations were done on client side

* Only active BICs are showed on initial load to reduce size

* Caching the BIC library on server so that it won't be created from scratch on each request (performance improvement)

* Total count of BICs is calculated on backend, instead of frontend

+ CSV, XML and JSON downloads now accept filter parameter to get only limited set of BICs

+ Added account checker when viewing a bank
