Patch 1

In Patch 1:
1)Improve loading performance for xls file
 create a new light method, ScTable::SetColWidthOnly() which is only set width
of the column. This method should only be called by filter which do not need
hanlde the position of drawing object.

2)Improve print preview performance
  Now MAXROW is 1,048,576. new SCROW[MAXROW+1] will cause a lot of memory and
time. Only create a proper size of array.
