Visual D v0.3.43 rc 1

changes from beta1:

• debug option: allow none of -debug and -release to be specified (and fix LDC never to receive
  the -d-debug option)
• some improvements to the C++ to D conversion wizard:
  • don't stop conversion after an unmatched } (this also caused other messages to not be displayed)
  • added support for sizeof without parenthesis
  • allow namespace scope in type names
  • allow virtual destructors
  • skip throw function specification
  • fix order of identifiers if "#define A B" is converted to an alias
• additional options: now replacing newline with space when adding to the command line
• compiling file for syntax check with LDC passed wrong command line option
