Addind 7GUIs examples (https://eugenkiss.github.io/7guis/). Currently implemented the first three: Counter, Temperature Converter and Flight Booker.
Fixes in IgnoreMatcher and ProjectDirectoryTree.
Window::runMainLoop now accepts an std::function<void()>, this allows to use lambdas with captures.
UITextInput when using only numbers allow to insert + and - at the beggining of the number.
Return Node* on Node::setFocus().
String::fromFloat and String::fromDouble will shrink the number as much as possible (delete extra 0 and .).
Improved drastically UIBorderDrawable performance.
Added Event::OnItemValueChange event and ItemValueEvent.
Added i18n function to UIWidget.
Remamed Node::addMouseClickListener to Node::onClick.
Added UI_SCROLLABLE flag and UINode::isScrollable to indicate if the widget implements some scrolling function and now UIScrollView will check if it can scroll by checking if the widget over is scrollable or not.
UISceneNode now implements loadLayoutFromString with const char* to avoid unnecessary std::string allocations.
Several fixes in UIListBox and UIDropDownList.
ecode:
Continued working on UIBuildSettings screen and Project Build configuration.
Added new markdown document with the UI Basics explanation.
