Bugfix for Safari 3.1.1 grid.js

grid.js misses a null check that makes it impossible to run FileVistaControl in Safari 3.1.1 at Mac and Windows XP.

The problem is located in:
function getStyleObject(className)
and the solution is to add a null check the same way as in the else if statement below.

if (document.styleSheets[s].rules[r].selectorText)

The problem appears only when there is some invalid selector text property in other style sheets that are added to the host page manually or by some other  control. The control works when there is no other css file interfering, as in the examples.

Anyway, the fix is included in v1.5.1, thanks for your feedback.
