#1664 Make the lblBuildTimestamp label align in center on the about dialog

[Terry Pascar]

This is a simple patch that makes the lblBuildTimestamp label aligned in the center instead of the right. Made this decision because i found it weird how it looks in the right after expanding the window compared to the static bitmap object at the top.
A pair of things to note is that i added a temporary text in the label for better visibility and that there is this change in the diff:

It is not related but it was made automatically.
Let me know anything. Thanks.

Post the patch.

The minsize removal may be harmless, but a bit of context would help.

Forgot to upload it originally, sorry.
Anyway here it is

Applied modified patch (see the commit) in [r14061], thank you.

wxALIGN_CENTRE was OK, sorry, but the style does not work as intended on wxGTK. I have just commited [r14062] centering via wxSizer instead.
