Improve searching of component browser entries (#5645)

Browse Source 
Closes #5102

This PR improves searching entries in the component browser. Now the searcher input is also matched to the code that a component would generate, and the best match of the two is used for filtering and sorting the components in the component browser.

#### Entry name formatting

Additionally, the component entry's displayed name format is changed to show the method's name first, followed by the type name in parentheses. This formatting fits better in the narrow columns of the component browser.

- [Added restoring of last project snapshot on shortcut.][4050]
- [Added contextual suggestions to argument dropdowns][4072]. Dropdowns will now
contain suggestions which are based on evaluated data.
- [Improved component browser entry filtering and sorting][5645]. The component
browser will now provide suggestions matching either the component's label or
the corresponding code.
