Add Process.as_dict() utility method

[GoogleCodeExporter]

This is something which comes up every now and then: an utility method which 
returns an hashable dictionary containing all the process information.
Usually, the user of this method intends to collect all process info in one 
shot and possibly pass the obtained data via json or similar data formats.
In general, this results in writing less and more-compact code since one 
doesn't have to look for AccessDenied exception every time as in:

p = psutil.Process(pid)
try:
    cwd = p.getcwd
except psutil.AccessDenied:
    cwd = None
try:
    ppid = p.ppid
except psutil.AccessDenied:
    ppid = None

...vs:

p = psutil.Process(pid)
data = p.as_dict()
cwd = data['cwd']
ppid = data['ppid']

This is now committed in r1341.
