[Tracker] Whitespace clean up

[Martyn Russell <martyn lanedo com>]

Hi all,

I have been meaning to write this mail for a while. We have a lot of 
white space inconsistencies in the code and a some trailing white spaces 
too (I am a big culprit on this).

I want to clean it all up and make sure we all use the same policy for 
white spacing in code.

First we need to decide on tabs vs spaces and where. I think last time 
this was discussed on IRC, people agreed to have spaces for function 
alignments and tabs for indentation. Do people still agree with this?

I would like to try to make sure this is the case in the code and at the 
same time remove any trailing white space. Choosing the right time for 
this is important too because we have some branches which are likely to 
have merge conflicts.

Currently active non-merged branches:

  mmc
  miner-web
  msword
  nautilus-extension
  nmo
  quad
  subqueries

When makes sense to make these changes?
