Win: Correctly show "IE" as HTML renderer if built with Edge support... but a supported version of Edge cannot be detected. Also bump the size of the fields in the DWEnv struct to be 65 characters in line with the size of Linux utsname fields so gcc fortify won't complain about possible truncation during strncpy().

# Set these here to change the version for all platforms
DW_MAJOR_VERSION=3
DW_MINOR_VERSION=1
