Project navigator file filtering

[LeonardoLarranaga]

Description

This pull request adds the ability to search files and folders in the navigator area. The following features were added:

1. Typing in the "Filter" textfield now searches through files and folders.
2. When a folder matches the filter, all of its content appears.
3. When searching, all of the folders get expanded.
4. The state of the folders that were expanded by the user before searching gets saved, so that when they finish searching, everything returns back to place.
5. When searching, the characters/words in the file and folder names that match the search get bold.
6. When there are no search results a label "No Filter Results" appears.
7. The search, just like in Xcode, is case-insensitive.

This is incredible work @LeonardoLarranaga! Two quick UI-related tweaks:

1. When "No Filter Results" appears as a result of not having any results, we should hide the root folder as well.
2. When filter text is present and if matches are found amongst files and/or folders, bolded text should have a primary label color and unbolded text should have a secondary label color. If parent folders are shown but do not have a match, than the unbolded text has a primary color.
