Make a sift tool

[GoogleCodeExporter]

It's a lot of work to dig through the data from stalk + collected.  Make a tool 
to sift through these rapidly and learn what was happening to the server.  The 
following files are currently collected:

2011_02_08_16_48_57-df
2011_02_08_16_48_57-diskstats
2011_02_08_16_48_57-innodbstatus1
2011_02_08_16_48_57-iostat
2011_02_08_16_48_57-iostat-overall
2011_02_08_16_48_57-lsof
2011_02_08_16_48_57-mpstat
2011_02_08_16_48_57-mpstat-overall
2011_02_08_16_48_57-mysqladmin
2011_02_08_16_48_57-netstat
2011_02_08_16_48_57-netstat_s
2011_02_08_16_48_57-processlist1
2011_02_08_16_48_57-procstat
2011_02_08_16_48_57-ps
2011_02_08_16_48_57-stacktrace
2011_02_08_16_48_57-top
2011_02_08_16_48_57-variables
2011_02_08_16_48_57-vmstat
2011_02_08_16_48_57-vmstat-overall

The tool should do the following, in a key-driven manner:

- show the timestamps for which there are samples, and let me navigate easily 
among them; for example, 'l' could select the most recent one, and 'j' and 'k' 
could navigate from one to the next.
- download needed tools such as diskstats, mext, align, and pmp
- summarize IO, disk usage, and CPU stats
- invoke external tools on files, such as diskstats, or 'less'
- summarize the processlist and InnoDB status
- show a help menu in response to '?'

Don't fetch the programs if they exist in the collected directory; don't break 
when the tool is called from a funny directory; pause after showing help
