t1.1: scrape one forum via ViewComments.cfm POST pagination

Spider fetches ViewComments.cfm?GdocForumID=N with vPerPage=500,
generates all page requests from page-1 metadata, and parses
each div.Cbox for comment_id, author, date, title, text, reg_title,
reg_desc. Handles span-wrapped comment text. Fixes UTF-8/windows-1251
meta-tag encoding mismatch. 9083 items, 15 empty-text (0.17%).

 Use https://www.townhall.virginia.gov/L/comments.cfm?GDocForumID=452 as the first forum. Scraper should be run manually at this step.
+ViewComments (townhall.virginia.gov/L/ViewComments.cfm?CommentID=#) appears to be raw list of all comments on forum - could be useful later for whole-scrape
+Append forum id to viewall per forum (townhall.virginia.gov/L/ViewComments.cfm?GdocForumID=452)
+Comments are hydrated in backend via js-cued button (AJAX?)

 * [ ] t1.2: initial analysis pipeline
 Write a simple pipeline for both - prefer non-concurrent/async from scraping run. Should be run manually, separate from scraper. You may use scrapy, but are not required to.
