Added truncatePath to utilities.zsh

Added `function truncatePath()` to utilities.zsh to take care of
truncation. This is pure zsh code, without calls to `sed`. Parameters
are:
   * $1 Path: string - the directory path to be truncated
   * $2 Length: integer - length to truncate to
   * $3 Delimiter: string - the delimiter to use
   * $4 From: string - "right" | "middle". If omited, assumes right.

Cleaned up code to use the new function instead.
