large file enhancements

[CodeBase]

I see that the 64-bit edition is now available. I no longer get errors when opening very large files. Good work.

Now, some suggestions to make opening large files even better.

1) It takes a long time for TextPad to open a very large file. Give the user the option to cancel the open.

2) When a very large file is open and you open the properties for that file, it takes a long time for the properties window to appear. This is presumably because TextPad is calculating the number of words and lines. TextPad should show the properties window immediately. It can do the word count in the background while the dialog is displayed. The word count would display as "Calculating..." until the count is done.
