New version of ANSIView. 

- Uses SyncTERM output speed emulation if available
- Server-side output throttling if client is non-SyncTERM, somewhat better than before
- Enable / disable screen pause
- Scrollbars
- No more static "background" UI graphic
- Uses new filebrowser.js
- Supports multiple local libraries
- Supports file descriptions for local libraries (requested by nolageek)
- Two additional "browser modules" included for access to online art archives (sixteencolors.net, thescene.electronicchicken.com)
- Read readme.txt if you want to use this.  It won't do anything until you follow the instructions

/* SixteenColors object
A simple interface between Synchronet 3.15+ and the sixteencolors.net API.
echicken -at- bbs.electronicchicken.com
With the exception of .getFile(), which returns a file as a string, all
other methods return arrays of objects.
Useful methods:
- .years()
- Returns a list of years, and how many packs each year has.
- .year(year)
- Returns a list of all packs in a year
- Each object in the array has a 'name' property, among others
- .pack(pack)
- Finds a pack by name (see above - not 'filename')
- Returns an object with various properties, most useful being
'files', which is an array
- Each object in the 'files' array has a 'file_location' property
- .getFile(file_location)
- Retrieves a file by file_location (see above)
- Returns the file as a string
Not-as-useful methods:
- .packs(page, rows)
- Returns 'page' of entries from the full list of packs in the archive
with 'rows' number of elements in the array.
- I haven't tried this, but I assume its return value will be similar
to .year(), possibly alphabetized
- .file(pack, name)
- Returns info about a given file in a given pack
- I didn't see much detail that you don't already get from .pack()
- .randomFiles(page, rows)
- Get a list of random files, I guess
- .randomPacks(page, rows)
- Get a list of random packs, I guess
Currently useless methods:
The API currently returns empty arrays for the following:
- .groups()
- .group(group)
- .artists()
- .artist()
- .month(year, month)
Errors:
On error, all methods log an error message and then return null. This is
lame, but it's all I need for now.
