Android: Add a new function for Android dw_file_open() which will open the URI that dw_file_browse() now saves at the end of the returned path. This is a hacky method of letting things function on Android... since Android seems to not let you open files with a pure path. Even if the file exists it will fail to open, you need to use the ugly Android URIs. Not sure if I will keep this solution or not, but committing it so Dynamic Windows Interface Builder will function on Android in the meantime. dw_file_open() just calls the system open() on non-Android platforms.
