Widget's name are the current way to retrieve them when using GML.
Presently, there is no way to differentiate two items that share the
same name.
`IncrementalSearchBanner` uses common names as "close_button" or
"next_button", prepend them with `incremental_search_banner_` avoid
collisions.
This fixes a bug where the close button of `CrashReporter` was confused
with the one of the search banner.
However, This solution isn't perfect, down the road, we should probably
find a way to warn about equal names and introduce something like
namespace to avoid huge prefixes.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Compared to traditional modal search, incremental search begins
matching as soon as the user starts typing, highlighting results
immediately. This refactors Itamar's work for HackStudio into a
common LibGUI widget to be used in all multi-line TextEditors.
