This commit is mainly intended to ease packaging for linux.
Unless environment variable AQUARIA_DATA_PATH is set, there are two
directories which are checked by the game:
If AQUARIA_DEFAULT_DATA_DIR is defined, it will chdir there for main
operation. If it's not defined, it chdirs into the directory where
the executable is located.
Then, if AQUARIA_EXTRA_DATA_DIR is defined, it will mount this directory
and all contents into the working path, so that the files present there
will override those from the working directory when accessed by the game.
Setting the environment variable AQUARIA_DATA_PATH will disable this
behavior altogether and use *only* AQUARIA_DATA_PATH as working dir.
This has the side effect that elements on the dark layer will now properly
wiggle when affected by water ripples.
Before this patch, the dark layer was always drawn above the postprocessed
screen content, unaffected.
This allows attaching multiple shader programs, processing the entire
screen as texture. Chaining shaders works, each shader will use
the output of the previous shader as input.
Fixes regression introduced in 0784d1b9df.
With a std::list it was okay to create shots while iterating with an
iterator, but not so with a std::vector.
Now using index access, which is safe with push_back() operations.

This repairs pixel/vertex shader code that was seemingly
experimented with during testing, but it was never used and no
shaders ever made it to the data files.
This fixes a glitch in the final boss' last form. Due to a missing
Beam::trace() call, the beam's angle was not updated,
and it always pointed into the upper left corner.

GL_CULL_FACE is effectively always disabled, except for quad strip
rendering, and keeping GL_CULL_FACE disabled there does not seem
to cause any visual artifacts.
Instead, it enhances skeletal animation possibilities
(e.g. flipping bone strips over without it disappearing)
Most hardcoded form == FORM_* checks all over the place have been replaced.
Now, forms change certain avatar properties, which are in turn checked
in the places that previously had these explicit form checks.
This allows specifying functionality via scripting, for additional forms
with new effects or a new combination of existing effects.
OT_HURT now deals damage of type DT_WALLHURT,
and by setting avatar->setDamageTarget(DT_WALLHURT, false) collision
with walls can be made harmless (exactly as nature form used to be).
Add related Lua functions:
+ setWorldType() - Change WT without actually switching to spirit form
+ setCanActivate()
+ avatar_setCanBurst()
+ avatar_canBurst()
+ avatar_setCanLockToWall()
+ avatar_canLockToWall()
+ avatar_setCanSwimAgainstCurrents()
+ avatar_canSwimAgainstCurrents()
+ getSceneColor()
+ DT_WALLHURT
This commit introduces a second pause mode:
Full game pause (as in menu), and world pause (as in spirit form).
All related checks are no longer done against WT_* constants,
but against the new world pause which is functionally equivalent,
but more flexible. Continuity::worldType is now only used to toggle
world pause correctly, and to apply some related graphical effects.
The world pause can also be controlled via script without actually
switching forms.
Added Lua functions:
+ node_setSpiritFreeze()
+ quad_setPauseLevel()
+ isWorldPaused()
+ setWorldPaused()
+ avatar_setShieldActive()
+ entity_isFillGrid()
* entity_setBoneLock() code made easier to read and not warn on no lock entity
+ entity_getMaxSpeedLerp()
+ entity_isEntityInside()
castSong() existing in the global Lua namespace caused it to be removed
and stored as an interface function as soon as a script was loaded.
The function was apparently never used in the game or other mod scripts,
thus renaming it now should be safe.
