Added regex support in ColorUtils for colors specified in hex using "0x" prefix
Added normalization fix in QuickView to enable color preview for colors starting with "0x"
replaced usage of hard-coded line numbers with concept of sections + lineOffset to enable adding additional tests without having to edit every line number in the file manually
Note: 'section' is defined as the css selector (class or id) that is used to group test data for different tests
renamed some css selectors to match their corresponding test for clarity
unit tests for color format with "0x" prefix
comments in unit test for clarity
