[Hallcsw] First pass at 'Shift Takers' / 'How-tos' instruction page

[Brad Sawatzky]

Hi all,

Shift taker's "Jump Page":
  https://hallcweb.jlab.org/wiki/index.php/Information_for_Shift_Takers
This needs to be the Shift taker's starting point. Please make sure it is correct!

And I started to flesh out the 'How tos' section here:
  https://hallcweb.jlab.org/wiki/index.php/How-to

Detector, and System experts must make sure basic reset/sanity check
information is provided within their sections!

Analysis Team: Please change the 'fixme' links for analysis on both pages and
point them at an Analysis Howto page.
