Issue #84: Paginate Actions

Addresses #84 
Added generic getPaginationData() function for findAndCountAll results.
Moved .get('/actions') logic to showActions() function.
Extend templateData in showBlocks() and showActions() with paginationData.
Local style is to use initialLowerCase for variables and InitialUpperCase for types. Declaring an argument of type BtUser here shadows the BtUser type. Also, it looks like this variable is not used within this function anyhow, so maybe remove it as an argument?
