NV: Add in 28th 2014 session; Committees seem missing

 > https://www.leg.state.nv.us/Session/28th2014Special/Committees/
 Looks like it's missing standing committees.
WA: Exception is raised for 404
LA: Update for bad links.
OR: Fix bill scraping to handle changed URLs.

Use HTML list of bills in session instead of fetching text file via FTP,
which appears to longer exist. Make other minor code changes to get
scraper working.
OR: Clean up code after eliminating FTP URLs

Replaces code that required FTP connections with code that uses
HTTP exclusively. Useful when scraping from behind a firewall.
Manually add a pesky bill title
LA: Shim around timeouts again.
NV: Raise no data for session error
UT: add 1990-1996 to ignored sessions
Merge branch 'master' into pr/482
MI: Events: Avoid new link buttons.
NM: Bills: Start to overhaul senate votes.

  Basically, the text extraction is a huge mess. by being a bit
  clever with the apparent placement of some of the random
  nonsense, we can use it to our advantage and get data back a bit
  more reliablly. I hate the formatting, but it seems to be consistent.

  Consistent is good.

  Issue tracked as DATA-298
NM: Bills: Finish off senate votes.

  This is the second half of the senate fixes. Looks like date formats
  changed a bit.

  Adding a failsafe to break if we don't parse again in the future.

  This addresses DATA-298
LA: Events: Update cruft stripping
CO: Legislators: Update photo URL
