fixed querying bug to search similar names

[bijanebrahimi]

fixed the bugs like Dropdown doesn't hide when have more usernames with the same beginning or Typeahead does not hide when using with queryBy name/username

to fix this, i change the code to only search for the word between user's cursor in textbox/inputbox and the space or delimiter character behind it. add this to last changes i made into the code to have different delimiter character for each user object, i added an delimiters option which is optional and defines all the possible delimiters. read the fuul documentation here
