0.19.5

• Windows: support Ctrl+C for terminating external commands.
• Windows: use the AssocQueryStringW shell API to launch non-exe commands rather than just running cmd.exe /C (cmd.exe is still used for failover).
• Windows: revisited exit code from sudo.
• export and source aliases are automatically created for eval --export and eval --source, respectively.
• The shell passes command line arguments to scripts, in both:
  ** run $SHELL <script_file_path> [args...], and
  ** source <script_file_path> [args...].
  ** $0 is the name of the script file, $1, $2 etc. are the rest of arguments, $# is the number of args not counting $0, and $@ is the concatenation of the arguments, including $0
