viewports, set flags to VP_DEFAULT_FLAGS

flags were getting un-initialized memory
it really didn't matter with the flags getting initialized
anyway
But once I added a new flag that didn't explicitly
set or clear the flag at init well here we are

set flags to VP_DEFAULT_FLAGS in viewport_set_defaults()

add the flags variable to the default vp's set to 0
(it was already initialized to 0 by bss, make it explicit)
