Perform search for movie title and retrieve all relevant data

[waxlamp]

This implements a search strategy that works by performing each of the following and stopping when a result is found:

1. Exact string match
2. Exact token subsequence match (e.g., terminator 2 will match Terminator 2: Judgment Day)
3. Substring match (e.g., terminator 2 will match the right movie as well as Exterminator 2)

It also provides a way to grab the Rotten Tomatoes URL from the search result, and to retrieve movie data from that URL, including:

• audience score
• critic score
• title
• year of release
• list of genres
• runtime
