REACH-54 Should support "." delimited searches

Search is implemented in the next scheme:
- the Flood receives search elements, each of them has `searchTags` from the Dynamo;
- `ModelsListView` besides generating categories fills `tagList` array and this array will be used for search;
- search returns limited number of most suitable elements (`weight` is criteria) (the Dynamo shows 15 elements but 15 elements take much space in the Flood. so it is set to 10);
- if nothing is found and search string contains special characters it generates regular expression from this string and does search using it;
- when Enter button is pressed there is no need to do search one more time, just pick the top result element.
replace all `\` with `\\`, `.` with `\.`, `*` with `\*`
