Deploy Export/Import Changes CSHTML file names to all lowercase

[hfloyd]

View files which are included with a Deploy Export for Re-Import are imported with all lowercase file names, so if you have a View file with mixed case, that is all lost on the Destination site.

Steps to reproduce

1. In your source website have some Views with mixed-case filenames (ex: TextPage.cshtml)
2. Do an Export, including schema-related files.
3. In a new site, Import, including the files.
4. Weep for you lost casing, since your file is now named "textpage.cshtml" 😢

Expected result

Filenames should be preserved.
