r45799: modified the ace:selectMenu and ace:comboBox layouts to make them more fluid and to avoid having to calculate rigid widths and heights for their internal nodes.

r45828: committed further adjustments to ace:comboBox and ace:selectMenu, consisting primarily of applying the state CSS classes (ui-state-required, ui-state-optional, and ui-state-error) to the main value container, instead of to the innermost span or text field
r45829: committed adjustments to showcase

Tested with ICEfaces 4 trunk r45834, Tomcat 7, FF 34, Chrome 43, IE 11, 10, 8.
There were no issues found with either Chrome or FF browsers.
When testing with any version of IE there is an issue with the showcase ace:selectMenu (any demo).
To reproduce:
In showcase open the ace:selectMenu > Overview demo. Click inside the ace:selectMenu component but not on the arrow icon. The list will open then quickly close. A subsequent click in the same manner will leave the menu open. This issue is only occurring with IE browsers and was not seen when tested with Jenkins build 1421 (July 27).

r46061: fix for preventing the list from opening and quickly closing the first time the component is clicked.

Tested with ICEfaces 4 trunk r46061. IE issue appears to be resolved however there is a console error now seen in all browsers when clicking inside the selectMenu (not the arrow icon).

IE 11 - SCRIPT5009: 'e' is undefined
