Add Alert to Horizontal Line

[shawnj]

I mentioned this in another thread but thought I'd make a clean formal reqest here.

Add the ability to add an Alert to the existing Drawing Tools - Horizontal Line. The Alert should have to option to only trigger one on a tick by tick update - ie. If we tick from below the line to above the line trigger the alert once or if tick from above the line to below the line trigger the alert once.

A very nice further addition would be to allow right clicking on the line and rearming the alarm. And even further polish would be allow the option to change the color of the line if the alarm was triggered vs a color for an armed but unfired alarm vs a color for a line with no alarm. And even more polish would be add the option to display text at either the left side of the screen or the right side of the screen, above the line, which show the price level the line is at (and perhaps some test showing the state of the alert.

thanks,
