only sending heartbeat on save

[alanhamlett]

Should also send a heartbeat when changing files, and every 2 minutes when editing the same file.

If what you send to wakatime is when you save a file, then that time means what you want to say. If, for example, you say that a project has worked 2 hours, does it mean that the time between modifications is 2 hours?

@sadalsuud That just means you were working in the project and saving file(s) many times, and that using your Timeout Preference (Default 15 minutes) that you worked 2 hours without breaks of more than 15 minutes.
