Updates libInjection

 * Updates libInjection repository to libinjection.github.io
 * Update libInjection to version 3.9.2, plus:
   - Pass the correct pointer to memmem()
     In parse_money(), if there is a "$foobar$", it calls memmem() to
     find it again. Wrong pointer can cause itself to backtrack in a
     dead loop and hang the entire process.
   - Addresses some issues reported by cppcheck, including an overflow
     on parse_slash.
