Quote string literals to calm YAML

It's not clear to me from YAML's spec that this should be necessary, but `rake jasmine` failed with the following in the previous version:


    telemachus learn_javascript [master= 43a0d4a]$ rake jasmine
    your tests are here:
      http://localhost:8888/
    rake aborted!
    (<unknown>): couldn't parse YAML at line 4 column 7

    Tasks: TOP => jasmine => jasmine:server
    (See full trace by running task with --trace)

Line 4, column 7 (by YAML's count) is line 5 of the file: this string - `**/*.js`. Only that one string seems to require quotes, but I quoted all the strings for the sake of consistency.

Other information, in case it's useful:

+ ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin11.3.0]
+ YAML 1.2.2
+ rake, version 0.9.2.2
+ jasmine (1.1.2), jasmine-core (1.1.0)

Thanks.
