Enhance regex in UIPath

[beuaaa]

No description provided.

[beuaaa]

Before version 0.6.0, only the name of a window could be described by a regex with the 'regex' parameter.
This regex description was possible only for the root entry of the UIPath.
The 'regex' parameter is now obsolete.

The key 'RegEx: ' in the UIPath syntax allows the user to describe a name with a Regex.
This regex description is possible for all the entries of the UIPath.

For example:

with Window(".* - Notepad||Window", regex=True):
	edit = left_click("Text Editor||Edit")

Must be coded with the new syntax:

with UIPath("RegEx: .* - Notepad||Window"):
	edit = left_click("Text Editor||Edit")

This parameter will be removed in the next release.
