Version 1.20a
- afl-multicore docs updated to reflect latest changes (by Mark Janssen).
- Fixed afl-multicore session check bug, that prevented adding additional
afl instances in normal mode (spotted by Mark Janssen).
- afl-multicore now properly updates its session file when adding additional
instances. afl-multikill was adapted accordingly.
- Simple interactive test mode added to afl-multicore.
