Acceptance criteria

• in all places where popups was used in previous versions, now they are replaced by overlay dialog.
• popups are limited in space using a scrollbar for content part. Overlay dialog resizes according to the actual amount of visible content.
• requests are made and processed according Zabbix MVC principles.
• popups are centered.

Decisions made

• overlay dialogs are displayed one on the top of other if there are more than one visible dialog on the screen.
• in scope of this task popup php files must be rewritten according to Zabbix MVC principles.

What's affected

• Frontend

UI
Javascript function PopUp() should be rewritten in such a way that instead of opening requested URL in a new popup window, the request should be made by AJAX and response should be used as a content of overlay dialogue.

Popup filters are realized by whole content reload. This must be changed in this task - content changes must be loaded by AJAX only.

Currently we do not open popups from other popups. After changes, there will be multiple places (widget configuration dialogs, map elements etc) where overlay dialogs will be opened from other overlay dialogs. Here the second dialogs will be displayed on the top of the first dialog (this is an initial concept which could be changed later if looks bad).

jQuery.Deferred() must be implemented to deal with delayed responses. Dialog resizes once the content is loaded.

Translation strings
Translation strings should not be changed.

Documentation changes
No changes in documentation needed. Printscreens in documentation are made in such a way that only popup content without window attributes is visible. Popups are consequently called "popups" and reflects also to modal windows.

In same way as context menus and hint boxes, page refresh closing also overlay dialog (popup) window. Must decide how to fix that.

(1) When executing scripts (Ping, Traceroute etc), overlay dialog is opened just few seconds later because dialogues are opened only after ajax response is received, but since script execution can take several seconds, user is forced to wait without any indicator, that something is actually happening. There should be some preloader or some other indicator that activity is started.

(2) Check all checkbox is not working after overlay dialog content is reloaded (for example, if filter is used).

Miks.Kronkalns RESOLVED in main commit (r74525).

(3) If text in overlay dialogue is very long, it is not wrapped into multiple lines, but continues as a single string. E.g., a text in item name column in key selection window (Configure -> Hosts -> Create item -> Key).
