Support the Escape key for cancelling changes

[asoltesz]

It would be nice to have the editing dialogs closed on pressing the Escape key (as usually expected with dialogs)

Hi @asoltesz

I'm glad my plugin gives you so much ideas and we can definitely add some to improve the plugin!
Don't hesitate to submit your PR if you already have implemented some of them and I'll merge your PR into the project as soon as possible.
I'll take a look for this specific feature, escape key press is something interesting to add to the plugin

If you find the plugin helpful, take a minute to star it on Github and rate it 5 stars on http://www.redmine.org/plugins/redmine_issue_dynamic_edit 👍

Have a good day too

@Ilogeek Yes, dynamic_edit is a great productivity booster makes one enthusiastic. (thanks for the plugin BTW)

I would love to contribute, although I have nonexistent Ruby/Rails skills and limited in Javascript. I will take a look and see if I can implement this.
