in most of files, including wx.h is not necessary, when only 2 or 3 wx files must be included.
Moreover, on windows, including wx.h sometimes create compil warnings about
shadowed vars defined in some specific windows headers.
Fix compile error
Fix string format to use %ld instead to work on clang in CADSTAR Archive importers
Add virtual destructor to CONNECTION in CADSTAR_ARCHIVE_PARSER
Fixed missing tokens that weren't parsed before:
- Danglers (in NET_SCH)
- Pin numbers (in SYMBOL)
- HidePinNames in both PART and PART::DEFINITION, defaulting it to false
Loading speed fixed by changing the way CADSTAR_ARCHIVE_PARSER::InsertAttributeAtEnd works (we now have a new attribute in each node to keep track of how many attributes there are). Now loads a 30,000 line file in 10seconds instead of 25 minutes!
