Serving root disk on Windows get's Access Denied in 0.12.*

[danny0838]

When serving disk root on Windows such as T:\ bottle always returns access denied when using static_file.

Below line needs fixed:

bottle/bottle.py

Line 2465 in 246c1f6

root = os.path.abspath(root) + os.sep

This seems to be done in 0.13, but it is not yet released, package installation via pip gets only 0.12.* and is vulnerable to this issue. Could you release a hotfix version in 0.12.* if 0.13.* won't be released soon?

Hello. I see you released 0.12.17 recently. Could you do a favor and provide a hotfix for this issue if 0.13.* is not ready yet?

Just change this line:

bottle/bottle.py

Line 2465 in 246c1f6

root = os.path.abspath(root) + os.sep

to:

root = os.path.join(os.path.abspath(root), '')

like 0.13 have done.
