Add case sensitive options for filters formulas

[AMBudnik]

Description

This feature is inspired by this thread https://forum.handsontable.com/t/by-value-filter-not-matches-as-expected/87/3.

Currently, filter forcefully converts all values into lowercase and then applies comparing algorithm.

Moved from GL #21
