Followable Output & Session Totals

New:

• remember total # likes & comments
  • printed after liking posts or commenting
• try/except log in error catch
• adjustable routes for log & r_log parameters for .gather_posts() method
• print outputs so user knows what's going on in:
  • .gather_posts() when:
    • collecting posts posts
    • checking new vs repeat posts
    • recording posts to log and r_log
  • .like_posts() before & after liking the posts
  • .comment() after commenting
• printed error if failure when trying to comment

Improved:

• sleep > time.sleep
• better greeting
• corrected sp on pwrd check
• better error for failure to gather posts
• number of posts collected in .gather_posts() only output once
  • after gathering the posts
  • was being output every 2 scrolls with total never being output
• check number of new & repeat posts to record before recording
  • save time/power if none to record
  • if none to record, skips recording
• lambda function for liking posts only defined once
  • was being defined each time it was being used
  • also removed redundant .click()
