Add project-wide string search to Web IDE
Frequently it is easier to locate code, particularly in unfamiliar or large projects, by searching the entire project for a function or constant. We should add this the Web IDE.
Proposal
- Add an interface for searching across the entire project, using strings and regexps
- Add an interface for reviewing results
