rneovim.git/busted, branch v0.2.0

tests: Rename neovim output handler to nvim

tests: Skip dumping elapsed times when not available

2017-04-10T00:51:50+00:00

Should provide some compatibility with old busted. And also removes duplicate 
parts from successString and skippedString, making them more like failureString 
and errorString which do not have times for technical reasons (busted for some 
reason did not yet compute duration before running the relevant handlers).

tests: Print description also at the end of the suite

tests: Use our own output handler on travis

2017-04-09T23:32:09+00:00

Reasoning:

1. gtest is better then something like utfTerminal, yet it is way too verbose.
2. gtest cannot be configured to show colors always.
3. Actually I am going to add a CMake target which will allow running tests 
   (especially, functional tests) in parallel, but this is not going to work 
   well with any of the default output handlers. Build in this case must be more 
   or less silent, yet debuggable. New handler does not support this in this 
   commit though.
