Adds Timeouts to avoid the app closing before the paste.

[leggettc18]

Fixes #56

Basically the app closes before the paste keystroke actually occurs, which then clears the clipboard (this particular behavior appears to be what changed between Odin and Hera). I added a 500 millisecond timeout before the actual close happens, both when the entry change signal occurs as well as the focus in or out of the main window. The following line of code is what actually does it.

Timeout.add(500, () => {
    close ();
    return false;
});

This does not feel like an ideal solution, ideally we would set it up so that the close function somehow waits for the keystroke to happen, or we could first store the clipboard data somewhere where the app could be closed without losing the clipboard data. I attempted to make each solution work but was unable to make it work. It would always either paste nothing or whatever was on my clipboard before the app was launched. More experimentation might yield a better solution, but for now I'm submitting this in the interest of getting something working.

Well actually I just saw #57... I didn't see any changes to what wasn't working as far as the auto-paste goes but I guess that appears to be working now based on the conversation. Feel free to close if that is the case.

EDIT: Well I pulled that branch and the issue this fixes still seems to be present...

@leggettc18 thanks for this! I went ahead and used this branch as a basis to clean up the closing behavior a bit more:

• moved the timeout and close behavior into a method since we want to do the same thing in multiple places
• moved the hide into that method as well since we always want to hide the window, wait, and then close it
• added a comment for future spelunkers

Awesome, glad I was able to help contribute in some small way, and learned a lot about Vala in the process. A bit frustrating that I couldn't figure out how to make clipboard storage work instead, would have been a much cleaner solution I would think.

@leggettc18 I think I know how I want to approach #17, which is basically:

• grab the current clipboard contents
• store that in a GSetting
• copy the emoji to the clipboard
• paste it
• restore the clipboard from GSettings

And then probably clear the GSetting for privacy reasons to ensure we're not keeping old Clipboard data around in our app's data
