Flat files folders, support for windows

[t19n]

Hi,
found out that the nested folders with flat files does not work on windows.
example:

└── users+
    ├─ $userId.tsx

on linux you would get auth+/$userId.tsx but on windows you get auth+\$userId.tsx,
seems to be that routeRegex in defaultOptions is not correct, at least does not support win backslashes .
