State should not be dirty

[bilogic]

If we were to

1. Load https://ondras.zarovi.cz/sql/demo/?keyword=default
2. Click on an empty space once
3. Try to close or jump to another URL
4. Browser prompts us to save
5. It should not, since no changes were made

Good suggestion. We will need a way to track (unsaved) changes, though.

I have gotten this working, but need to understand which of my PRs you can accept so that I can find a suitable spot to PR this in. Thank you.

temporary parking spot for my code

// globals.js
window.onbeforeunload = function (e) {
    if (SQL.Designer.is_dirty) {
        return "" /* some browsers will show this text, some won't. */;
    } else {
        return undefined;
    }
};


// wwwsqldesigner.js
SQL.Designer = function () {
    SQL.Designer = this;

    this.is_dirty = false;

SQL.Designer.prototype.dirty = function (value, remarks) {
    if (value === undefined) {
        value = true;
    }
    this.is_dirty = value;
    console.log("Dirty flag set to", this.is_dirty, remarks);
};


// rowmanager.js - nothing
// row.js::update, up, down, changeComment, addRelation, removeRelation, addKey, removeKey, destroy
SQL.Designer.dirty();

// io.js 
SQL.Designer.dirty(false, "serversave");
SQL.Designer.dirty(false, "loadresponse");

Sorry for being late all the time. As far as I can tell, there is only one PR pending right now (keyboard shortcuts); please feel free to submit this one based on the current master.
