Also compress the template code

cinera_player_pre.js: Fix bug in which onRefChanged() tried to call
player.jumpToNextMarker(); before the player was ready. This could
happen if its first marker's timecode is 0:00 and medium is :afk

Enable Theatre mode to work in containers styled with max-width or
max-height

Also fix the inotify loop, augment the index (the .metadata files) to
contain data useful for insobot, and futureproof UpgradeDB()

Flags:

    * -e Examine Index
        Just pop an -e on the end of your usual list of flags
    * -u Update Interval (was -U)

Also correctly skip .hmml files for credentials-related reasons

Also add user-select: none

This also changes the hardcoded, unintegrated output to wrap cineraMenus
and cineraPlayerContainer in a <div>, as newly reflected in the example
template_player.html

Introduce nullTopic, visually represent the media in annotations and
default to "exclusive" mode

Keeps the results looking more consistent between various display widths

The template buffers no longer contain indentation spaces at the start
or a \n at the end. This removes any weirdness from template composition

Also remove the cleanup code added in 0.5.22

The actual bug was that MarkerIndex wasn't being incremented for
HMML_CATEGORY markers mid-annotation... (HMML_MEMBER and HMML_PROJECT
were fine.)

You would find @members and ~projects ending up in cinera_topics.css if
they were preceded by a topic :category in their annotation

Also fail gracefully if supplied with an .hmml file containing an
incomplete [video] node, or a template containing tags whose buffers
cannot be populated

Remove environment variable CINERA_INTEGRATE because this is meaningless
now that the default template locations are blank

Flags
    -t Template Directory (was Player Template Location)
    -y Player Template Location

Bug Fixes
    Correctly skip annotation sets that couldn't be processed for
    various reasons
    Fix crash caused by <!-- __CINERA_INDEX__ --> tag in a player
    template, because its buffer was being freed
    Fix 2048 bytes leak per processed set of annotations

Specifically, with the addition of MODE_ONESHOT in v0.5.12 we must allow
for the possibility of being in both that mode and MODE_INTEGRATE

This sets cinera to "oneshot mode" which makes a Project Edition instance
quit after syncing from annotation files in project input directory

Relative to the Base:
    -a sets the player location
    -n sets the index location

Tweak flags, and add -B to set Base URL (necessary if setting -a or -n)

New template tags:
    __CINERA_URL__
    __CINERA_VIDEO_ID__

Bump DB version: 2
    index_header now contains the Index and Player Locations

This is hardcoded for now, for ease of use, pending the config system

Also add Medium to the ProjectInfo array, to save users having to set
this with -m (which option remains available to them)

Reorganise the CSS, Images and JS files back to their location in the
same directory, since a default invocation of the program assumes they
are in the same directory as the Root Directory, to hopefully alleviate
some potential user frustration thanks to the requirement to set their
locations (with -c, -i and -j) before any usable output is produced

-s flag sets the style / theme
Also some general code clean-up and repo organisation

hmdshow_2016_03 uses :multimedia
Various riscy and hero annotations may use :hat
