osPID-Front-End v0.6 modded to work with (hairykiwi) osPID-Firmware v1.61i

NB: This is 'working, but very much in early development'.

Changes:
- Comm.pde - Status messages section expanded to include messages from Type 4
  and 5 profiles.
- IOCards.pde - r3.getItem(1).setState(true); // Set default to digital output.
- osPID_FrontEnd.pde - user preferences edited: windowSpan = 8 minutes,
  refreshRate = 1000 ms, outputFileName = "Run_0xxx.txt"
- SPProfile.pde - expanded to include profile info (textual and graphic) for
  Type 4 and 5 profiles.
- RoHS_Elgento024 - as used to successfully reflow solder the OTM-02 prototype.
- RoHS_Elgento025 - based on RoHS_Elgento024, with peak temp increased 2 degC +
  buzz added when temperature increases and descends through 217 degC.
- Demo_All_Profiles - A simple demo to show that the original three profile
  types can function alongside the new Type 4 and Type 5 profiles.

Issues:
Specific to the above mods:
- Time in Type 5 profiles is not properly reported in Front-End. (This is likely
  a Firmware issue, but a rework there will also require a complete rework of
  afffected Front-End sections.)
Other Issues:
- When profile running, loaded profile should be displayed in Status window -
  it's possible to load a profile, run it AND then display another. As a result
  a mis-match of what's running vs being displayed can occur.
- Loaded profile could be displayed, along with run/stop control on RUN tab.
