LOK - Calc: Text is not visible in cell when entering numerical input

Problem
The issue occurs when you double click and enter a numerical input in
a cell which belongs to one of the front colums.

Findings
After a bit of investigation I detected that the problem shows up when
the spreedsheet width is increased by invoking
ScViewData::SetMaxTiledCol.
Indeed the problem occurs whenever the spreadsheet width is larger
than 2^16 twips.

Solution
By changing the type of some variables from sal_uInt16 to long in all
involved contexts, the problem disappeared.
