removed #=[] documentation syntax

For now, used '#| ' instead. Still need to change S26 to use this, too. :)
[Druid::Game] added workaround for RT #57852
[Druid::Player] added workaround for RT #75858
[Druid::Webapp] removed for now

We're not converting Web.pm to Rakudo master right now, and this class isn't
essential to Druid anyway. Better to just remove it for now.
[Test::Ix] s/undef/Any/
[Test::Ix] eagerified a gather without take

Using a dummy array as a target, we can cause the gather block to run. Since
the gather block has no 'take' in it, the dummy array will be empty.
[t/01-game-rules.t] added 'our' to everything
[Druid::Game::Subject] changed membership idiom

There are different ways to test for array membership. This is one:

  @array ~~ (*, $elem, *)

But there's a bug in Rakudo master which makes this not work when $elem is
an instance of a user-defined class. Instead, switched to this idiom:

  any(@array) === $elem

It works, and it probably reads a bit better, too.
[Druid::Base] worked around Rakudo parsefail

Rakudo currently can't parse comments starting with '#= '. Changing to
'# = ' for the time being.
[Druid] put rules in a grammar so that they work
[Druid::Game] initialized attribute to 0

Nowadays (in ng) not initializing something to 0 and then doing a
numeric comparison triggers an undefinedness warning.
create a panda compatible META.info
bring the simpler part of Test::Ix up to snuff.
ignore blib directory.
use MAIN sub in druid "binary"
move druid bin to bin/
assorted modernizations
"defined" is no longer a prefix operator.
workaround no longer necessary
Player::BUILD now works properly.
