Workaround for bootstrap css to build into dist
Introduced new abstract chart class to concentrate shared functionality between charts
Implemented charts zooming (3months, 6months, YTD, different years, etc.)
Updated fd.data.months to be simple array of yearMonths instead of array of objects (convert to array of objects using fd.util.pack() function)
Removed unnecessary commented code block
Implemented shifting charts by 1,3 months left, right
Fixed navigation to /# URL location on chart view select (the page jumps to the top - awkward) - by event.preventDefault()
Set default chart view on first switch to chart's tab
Fixed showing AccountBalance tab + added Net Worth balance
Improved category spend / income charts
