Make glob string property settable
Extend folder search glob when removing result and holding option

This is a quick way to exclude the file from future searches.
Using ⌘G after a folder search no longer visits removed documents
Add option to search linked files (rather than folders)

Also reworked API slightly to make things more explicit.
Skip searching binary files

Binary files are identified by containing a null byte (after applying encoding heuristics and decoding potential UTF-16 etc.).
Add new folder search options to action/options menu
Strip diacritics and combining marks when asciifying

Previously we would transliterate æ → ae and å → a (via iconv) but something like é became 'e.
