Search / Block UI Bugs

[TroyNeubauer]

1. Strange wrapping when right clicking block:
   

2. Audio sink is not the first search result dispite name matching exactly

Putting this here mostly for me. The search could look like:

1. Split block names into tokens
2. Filter out all blocks which do not have at least one token existing in the search query
3. Let n be the number of tokens in the block name with the highest number of tokens in the array of filtered blocks
4. If the first token exists in the query give n points to the result
5. If the second token exists in the query give n-1 points to the result as so on

The search results for "audio sink" would be:
Audio Sink - 5pts
Audio Source - 3pts
Audio File Source - 3pts
SDR Sink - 2pts
File Sink - 2pts
Console Sink - 2pts
