AutoItLibrary Install Fails when Python path contains spaces (fix included)

[HW71]

Originally reported as Issue 30 in old GoogleCode project.

What steps will reproduce the problem?

1. Install Python to a path with a space, e.g. "C:\Program Files\python27"
2. Execute python setup.py install

What is the expected output? What do you see instead?
I expect the install to complete successfully. Instead I get this:

python setup.py install
%SYSTEMROOT%\system32\regsvr32.exe /S C:\Program Files\Python27\Lib\site-package
s\AutoItLibrary\lib\AutoItX3.dll
Traceback (most recent call last):
File "setup.py", line 70, in
subprocess.check_call(cmd, shell=True)
File "C:\Program Files\Python27\lib\subprocess.py", line 540, in check_call
raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '%SYSTEMROOT%\system32\regsvr32.exe /S C:
\Program Files\Python27\Lib\site-packages\AutoItLibrary\lib\AutoItX3.dll' return
ed non-zero exit status 3

What version of the product are you using? On what operating system?
AutoItLibrary 1.1, Windows XP

Please provide any additional information below.
I have attached a working setup.py along with a diff file.
