Support multiline prompt in tcsh

Browse Source 
Notes:

- I had to launch script twice because tcsh does not actually support multiline
  prompt: it squashes everything into one line.
- Thus I had to add POWERLINE_TCSH_NO_ABOVE_PROMPT: running python twice is not
  nice for performance.
- Due to 1) tcsh shifting rprompt by 1 and 2) tcsh not accepting %{%}-escaped
  color section at the very end of rprompt (actually it is accepting it, just
  makes user input colored as that section) I had to reduce computed width by 2.
- As running powerline command in precmd modifies status code I had to use
  POWERLINE_STATUS variable to save status.
- As tcsh does not accept names that start with underscore non-API powerline
  variables do not start with underscore.
