Handle alternative log format for process start

Some phones (like my samsung) do not log the 'Start proc ...' line in
logcat to indicate process start.  In my case it does log a line like

E/dalvikvm(pid): >>>>>> com.my.package [ more stuff ]

This commit adds support for that format to pidcat.
Merge pull request #73 from ahupp/master

Handle alternative start proc log line
Fix failure to match new format start messages

For low pids there's a space in front of the PID in the log message.
All my testing was on high pids :(
Merge pull request #74 from ahupp/fix-space-bug

Fix failure to match new format start messages
Support any number of spaces before the PID.
