- Added Option to set a prefix anchor integer using "FuzzyAutocompletePrefixAnchor". This will require the completion items to match the first "x" letters you type ("x" being the integer you set).  For example, if you wanted completions to match the first 3 characters you type, you would set the option: "defaults write com.apple.dt.Xcode FuzzyAutocompletePrefixAnchor -integer 3".  If the prefix anchor is set to 0 (or not set at all), the option is turned off and the default behavior is used.
- Corrected typos in README: setting option values using `defaults write` requires `com.apple.dt.Xcode` and NOT `com.apple.dt.xcode` (note lowercase 'x').  The option doesn't work if you use a lowercase 'x' in 'Xcode'.
- Added explanation of the "Prefix Anchor" option in the README
- Corrected small typo in Readme
- Removed brackets around `[x]` in the README Prefix Anchor option to prevent confusion.
