Nathan Scott b2a8b2426e Tweak style guide wording around single code statements 
There was wording about brace-enclosing single code statements
being 'strongly encouraged' - this isn't consistently used and
IMO it introduces unnecessary noise in otherwise neat, concise
code.

I've reworded (dropped) this section and also fixed a handful
of minor typos while reading this doc a little more carefully.

Nathan Scott f704baeb82 Drop unused global ProcessList memory fields 
The global ProcessList structure contains a couple of unused
fields.  'sharedMem' has never been used by any Meter, since
its not been anything other than zero in Linux /proc/meminfo
for many, many years.  The freeMem field is only used in the
usedMem calculation, so it can reside on the stack like some
other memory variables used within-calculations-only and not
exposed to the user via a Meter.

Nathan Scott fee217551c Drop unneeded parameters to the ScreenManager constructor 
All calls to ScreenManager_new always pass the same first
five values, the orientation is always HORIZONTAL and the
y1 parameter is always the height of the passed-in header
struct pointer.  I think its safe to assert at this point
that no VERTICAL orientation will arrive (if it does, its
no harm in re-adding this then) - so we can remove unused
conditionals (and TODOs) based on orientation too.
