2f3f75965a Fixed a 'Use of uninitialized value' error in Diskstats->print_deltas() 
It's not clear to me how this can even happen, as the variable is
package-scoped and set during compilation, but this should fix it.

b0f7bc4fc6 Tweaks requested by Baron, plus fixes. 
Tweaks:
* --headers command line option, which can be used to
        enable/disable the automatic headers, and the
        automatic empty lines between samples.
* --show-timestamps, which changes the #ts line with
        a timestamp in the HH:MM:SS format.
* Always use ReadKeyMini, even when we have Term::ReadKey.
        In the latter case, use the Term::ReadKey functions,
        but if they fail, try again with our own versions.

Fix:
Looks like I forgot to actually enable the "save the current, first
and last" samples. This is now on. It should mean faster and better
output when changing --group-by modes.

7c4c186978 Change how Diskstats waits for its first handful of samples. 
This fixes two bugs -- One a rounding error, one a desyncronization
between the main program and the data gathering daemon.

Additionally, it changes how the daemon prints the very first
sample. Before it would unconditionally wait until the time was
%$sample-time, which meant that in a worst case scenario,
a user could be left waiting for a while before seeing a line
of output.
This commit changes that first wait to only sleep if less
than 20% away from %$sample-time.

f173069109 Stop using /(?=)/ since /.+/ is good enough. 
Originally, DiskstatsMenu differentiated between an empty pattern
entered by the user (which in the shell version meant "match all")
and any other valid pattern by replacing it with /(?=)/.

However, Diskstats now carries the original string, inside the
OptionParser object, so the above was redundant.

eaae370f81 Removed the handling of the partition format. 
/proc/diskstats actually has two formats, one for devices, one for
partitions. The latter wasn't handled by the original pt-diskstats,
but one of the previous commits introducing some minimal handling
for that. This commit removes that, since the partition format
doesn't have enough information to be useful.
