The Asset index utility chokes on folders with `.` in the name

[angrybrad]

Steps to reproduce

1. On a fresh Craft install, create a new local Asset Volume (set the path to ./uploads, for example).
2. On the file system, go to the uploads folder and create a foo.bar folder inside of it and make there is at least one image inside of it.
3. In the control panel go to Utilities->Asset Indexes and run the utility.
4. Notice the flash error.

Note that manually creating the foo.bar subfolder from the Asset index page in the control panel works fine.
