Changed 'tick' variables to 64 bit

- This fixes an issue with timers that stop working after about 24-49
  days when the tick overflows (note that this may happen much earlier
  than that, and at hard to predict times, on some systems)
- Updated the RDTSC help message in the configure script to also warn
  users about issues with SpeedStep enabled systems.
- On Windows, tick() still has a resolution of 10~15ms (or even as low
  as 100ms on some systems). A TODO comment (thanks, Ai4rei) was added
  for a follow-up patch, as I want this one to be as small as possible)
- Note: on Windows versions earlier than 6.x (Vista, Server 2008), the
  tick overflow issue is NOT fixed, since they don't support the
  function used to retrieve a 64 bit tick. This isn't a big issue, since
  those platforms are already - or going soon to be - out of their
  extended support period, and it's already advisable to upgrade, for
  other reasons. If you're the unfortunate user of such a system, it is
  recommended that you reboot your machine at least once every 49 days
  for Hercules to work reliably.
- Note: To clear some doubts, since I've already been asked, this has
  absolutely NOTHING to do with 32/64 bit CPUs or OSes. It's all about
  a variable's size, not the size of registers of your CPU, and your
  32bit CPU will be able to handle this just fine.
