Fix data validation issues (#975)
* Fix `SetDropList` to allow XML special characters

* This closes #971, allow quotation marks in SetDropList()

This patch included a XML entity mapping table instead of
xml.EscapeText() to be fully compatible with Microsoft Excel.

* This closes #972, allow more than 255 bytes of validation formulas

This patch changed the string length calculation unit of data
validation formulas from UTF-8 bytes to UTF-16 code units.

* Add unit tests for SetDropList()

* Fix: allow MaxFloat64 to be used in validation range

17 decimal significant digits should be more than enough to represent
every IEEE-754 double-precision float number without losing precision,
and numbers in this form will never reach the Excel limitation of 255
UTF-16 code units.

Veniamin Albaev dc01264562 Huge refactorig for consistent col/row numbering (#356)
* Huge refactorig for consistent col/row numbering

Started from simply changing ToALphaString()/TitleToNumber() logic and related fixes.
But have to go deeper, do fixes, after do related fixes and again and again.

Major improvements:

1. Tests made stronger again (But still be weak).
2. "Empty" returns for incorrect input replaces with panic.
3. Check for correct col/row/cell naming & addressing by default.
4. Removed huge amount of duplicated code.
5. Removed ToALphaString(), TitleToNumber() and it helpers functions at all,
and replaced with SplitCellName(), JoinCellName(), ColumnNameToNumber(), ColumnNumberToName(), CellNameToCoordinates(), CoordinatesToCellName().
6. Minor fixes for internal variable naming for code readability (ex. col, row for input params, colIdx, rowIdx for slice indexes etc).

* Formatting fixes
