Add timestamps to each message

Enabled with the -t flag. Fixes #9

@JakeWharton Just a friendly ping.

This is kind of an eye sore. I was thinking about right-aligning the time and omitting the date and millis since they're relatively useless information.

[marczych]

I think the millisecond resolution is actually pretty useful when you get a flurry of logs in a short period of time. I agree with you about removing the date, though.

On the topic of making it pretty, it looks especially ugly when text wraps:

I'm not sure what to do about that... I tried a different color to differentiate the timestamp from the log message but couldn't find one that I liked.

Hi, I've rebased @marczych's commit to the latest master and resolved conflicts (specifically, between the -t short option for timestamps and the already existing -t flag for tags) in PR #82. This is a really useful feature, let's merge it in.
