Refined the grammar for filtering workouts (#4531)

* Added support to filter for numbers in the description / title / tags,
  similar to #4529
* Added quoted strings when filtering in description / title / tags:
  * Words can be grouped by putting them in quotes to search for exact
    matches
  * Keywords can be put in quotes to strip their special meaning
  * Examples: "Power Builder 60", "Power" 60
  * Added this also to TrainerDay, keeping the syntax similar
* Adjusted the autocompletion to not propose keywords when within open
  quotes
