fix(filters): provide flag to disable special chars input filter parsing

[ghiscoding]

• Slickgrid-Universal is by default parsing some special characters (<, >, =, *) when found in filter input value but in some rare occasion the user might have data that includes these special chars and might want to disable the parsing, this PR provide a new flag autoParseInputFilterOperator that will disable parsing when set to false and search the value as it is
• this option is available from both the GridOption and the Column, the latter will always have precedence
• ref Stack Overflow In angular slickgrid, the records with special characters "<" , "=" are not getting filtered
