Android: Change dw_file_browse() to return URIs or paths on Android. Paths will be returned if either DW_DIRECTORY_OPEN or DW_FILE_PATH flags are specified. Otherwise a URI may be returned. The double string method of returning both path and URI has been removed. DW_FILE_PATH and DW_FILE_MASK have been added, but are really only used on Android. __DW_MOBILE__ will be defined on Mobile platforms such as iOS and Android. __DW_DESKTOP__ will be defined on most other desktop operating systems.

# Set these here to change the version for all platforms
DW_MAJOR_VERSION=3
