GlFilteredSearch > Do not complete token on space

There have been a lot of issues with filtered search with token values with spaces. For example a milestone with the value of My milestone will only be searchable if we surround the text in quotes "My Milestone".

A lot of users don't know that this is an option. Also, before users figure this out they will probably try and search using the space bar My + space + Milestone but when the user hits the space bar the token completes.

There are a lot of issues scattered I will organize but this issue is a request to remove the need to surround text with " and to not create a new token when a user adds a space to the search string.
