v0.50.1

I made an error with the version numbering of this release. The version number in the window title bar will say v0.50.0 even though this is v0.50.01.

Rather than change the release I'll just note it here. It's not that important.

Changes since v0.50.0

• Bug fixes

• correct identification of ELF entry point
  • failed if the entry point was outside the .text section
  • this fixes the new ELF version of LodeRunner
