[CALL FOR REVIEW] VCLAuto patch -- Fix unstable problems of automation scripts

[Linyi Li <li...@gmail.com>]

Hi,

When I run GUI automation test cases, some test cases are not stable.

To increase the robustness, I created this patch. Solved following problems:

 1. SubtotalsFunctions.java: Changed a control to treelistbox, changed
coordinate positioning to treelistbox selection. Which made more precise
positioning.

2. Sometimes navigator dialog will block operations of 3 editor(word
process/spreasheet/presentation). Cleaned user installation directory
before each test case.

3. testSortOptionsIncludeFormats: Sample file for this test case is not
correct.

I created on defect to track it:

Pls help to review it. Thanks~

Best wishes.
