Modify the sample rate module output to be (slightly) easier to understand.

Browse Source 
* add dot11rate_label() which returns Mb or MCS based on legacy or HT
* use it everywhere dot11rate() is used
* in the "current selection" part at the top of the debugging output,
  otuput what the rate itself is rather than the rix. The rate index
  (rix) has very little meaning to normal humans who don't know how
  to find the PHY settings for each of the chipsets; pointing out the
  rix rate and type is likely more useful.
