Fix `--restart` option

More info at #96.

Replace `Trollop` with `Optimist`

More info in #94 .

Also fix some issues in #86 and #91 (with improvement in #93).

The first stable version, refactored and tested

FileWatcher renamed to Filewatcher (now follows the generally accepted rules of naming).

Events renamed:

Before	After
changed	updated
new	created
delete	deleted

The executable file now executes the command only once by default when several files are changed. To return the old behavior, the option --every is added.

For the Ruby API, Hash with changes to the current snapshot are now available, and you are free to process any change as you wish.

Tests are now very long (we will improve it), but (hopefully) reliable.

Congratulations!

New --restart and --dontwait options

The --restart option restarts the command when changes happens on the file system. The --dontwait starts the command when filewatcher is started. To start a webserver and have it automatically restart when html files are updated:

$ filewatcher --dontwait --restart "*.html" "python -m SimpleHTTPServer"

Support for absolute and globbed paths

Absolute paths and globbed paths now work properly.

FileWatcher.new(["/tmp/"]).watch do |filename|
  ...
end

FileWatcher.new(["/tmp/**"]).watch do |filename|
  ...
end

Exit cleanly from ctrl-c

This prevents a stack trace from printing on exit.
