New Revision: 4980

URL: http://svn.digium.com/view/dahdi?view=rev&rev=4980
Log:
Fix display of indirect registers and streamline their setting.

* This commit fixes display of indirect registers through the chipregs
  (formly "slics") procfs file. Only the low byte was displayed.
* It also deprecates previous {RW}S in favour of {RW}I. The prevois
  style is still allowed but deprecated, and thus previous scripts will
  still work.
