Adding Mods for v2014.4.16

Mob fixes

Added UndeadWitch, UndeadTroll and Troll to Mob data

It now only need be a name that does not contain a comma.

This update triggered cascading map ID changes. This system needs
rewriting to handle automatic adjustment of map IDs.

Perhaps the logging format should be changed to log the stable ID?

This handles funky newlines and trims trailing junk, albeit in a not
particularly elegant way.

Second range parameter is exclusive

Rarely, 24 hour blocks will still contain undefined records.

These are infrequent enough to not impede overall analysis (you can use
mv.heap.def.filterAll(); dc.redrawAll() to confirm), but when loading in
multiple datasets, can have a substantial number of records occurring
before them.

This should become a non-issue again when the scrubber keeps track of state
outside of the logs being collated.

It was redundant, given the title of using your own datasets anyway.

This should make the distinction between loading own files and using the
latest dataset clearer.

The equal height psuedo-columns could be applicable to the chart columns too.

Generic column layout based on:
http://nicolasgallagher.com/multiple-backgrounds-and-borders-with-css2/demo/backgrounds.html

This also adjusts the method for comparing filters, allowing a chart to
define a "filterCompare" method that will be used to compare filters if
available.
This finally removes the date chart special case for setting filters.

Array instance checking will now use foo instanceof Array instead of
typeof(foo) == "array", which was unreliable (sometimes it's "object").

Trellis chart brush containers will now redraw the brush when set
externally.

renderBrush no longer takes brushG as a parameter. I'm not sure what I
was thinking when I made it so.

The deselected area will not yet fade.

The trellis chart still requires substantial refactoring and consistency
fixes; I'm not sure that the parameter specifications are currently
correct.

No broadcasting functionality yet.

d3.select(this) is wasteful and not always reliable

Deselecting areas, applying filters, and broadcasting filters are not
implemented yet.

Before, if you were quick or your connection was slow, you could select the
files before mv.init registers the callback.

This left things stuck, either requiring another set of files to be
selected, or a refresh of the page.

This closes #18.

mv.loader.use takes an array of URLs, which are fetched via d3.xhr.

This also restructures mv.loader to refactor out some shared functionality
between mv.loader.use and the file selector change events.
mv.loader could still use some cleanup.

http://css-tricks.com/examples/ButtonMaker/ makes a pretty neat css button.
Hopefully, it's visually attractive enough so people in a hurry know where
to go. :)

Upstream merge on exposing xhr.responseType pending.

Based off bootstrap

The inner loader closure was redundant. Apparently I really like closures
during late night coding.

main.js should no longer have to deal with raw loading events; only UI
specific callbacks.

Also remove a stray curly brace

.zip must be at the end of the file name.

Progress bars are not fully descriptive in this mode yet

This also alters the mv.loader interface.
The onprogress callback now takes current and total.
The each callback is now passed an after parameter, to be called when it's
done.

This should all be done by delta updates.

d3 joins, while fun, aren't really the tool for the job here. :)
