Updated README and RELEASE to match 0.5.2: xterm-256color check.
Removed auto formatter on read of Go files, now handled by vim-gocode.

The August 28th, 2013 commit (65d05b3c9a) of the bundle vim-gocode now
automatically calls the formatter on save. Hence the prior formatter
code was a duplicate of a sorts, although this means that improperly
formatted Go code will still be improperly formatted on BufRead.
Updated README to reflect Go code formatting on save.

This corresponds to RELEASE 0.5.3.
Updated RELEASE notes for 0.5.3: vim-gocode bundle handles format on save.
Releasing 0.5.3: Go code is formatted on save.
