* Move pkhex.drawing calls out of form constructors
designer doesn't like it; if Main can't be designed then there's some
call that it can't process for whatever reason
* Add netcore3 targeting
Closes#2198 by adding a netcore3 build option
Closes#2391 by retaining designer functionality and net46 builds
move distinct filter to reflectutil as it is spitting out
inherited(overriden) property names after the current class' property
name.
remove original (default) memory strings; had removed Items.Clear()
earlier (why would I need to clear if there was nothing there?) but
there was something there needing to be cleared. Remove the useless
initialization to fix that :)
Thanks Davil!
