[Added fix to avoid different colors in screen mode.
By default in vim different colors are displayed when used from screen mode and when used directly from bash (without screen).
The fix resolves the issue.]
[Added plugin colorscheme for kkruby scheme, its good for the eye.
Added plugin vim-airline, is used by vim-airline to display branch name in the status line.
Added leader mapping to open vimrc file and to execute vimrc when modifications are done (\v, \V).
By set default set colors 't_Co' to 256, be default its set to 8, used when using colorscheme.]
[Changed hardstatus line for screenrc file.
Commented out the previous one was little boring on purple background.
Now host and username at the left and topen screens in center and date time at the right.
