Tons of changes to correct the position of event animations in a slightly prettier way than the previous way.
This time the offsets within animations aren't changed. Instead the offsets are changed for each event.

bonus.cpp
*) Changed the method call that disables a default animation offset.

anim.cpp, anim.h
*) Removed method to copy offsets.
*) Refactored method name for the method that disables a default animation offset.

levelload.h
*) Changed the enemy path loading

bridge.cpp, event.cpp, eventframe.cpp, event.h
*) Changed method calls that happen with certain behaviors
*) Added an extra offset that can be set to correct positons.

playerframe.cpp
*) Changed code to understand the extra offset

anim.h, anim.cpp
*) Frame by frame X-offsets are being shifted two bits up now.
*) The animation-wide X-offset has been removed because it does not exist.

levelload.cpp, bonus.cpp
*) Due to the changes in anim.cpp and anim.h the animation loading code had to be changed.

bridge.cpp
*) Bridges should ignore an animation's Y-offset if it is zero.

event.h, event.cpp
*) Added a getAnim method to make life easier.
*) Events with certain behaviors need some fiddling with Y-offsets so they can be drawn correctly.

playerframe.cpp
*) The invincibility animation should also ignore Y-offsets.

Add initial decoding of FF frames. Works with shareware intro. Looks nice with level over, but repeat needs a small fix. 

Enforced case-sensitivity for file names, accessible by defining UPPERCASE_FILENAMES or LOWERCASE_FILENAMES.

Moved guardian energy bars to the foreground. Changed the way post-level bonus levels and cutscenes are launched. Disabled bonus levels in multiplayer.

Changed animation handling so that it does not require a level to exist. Improved bonus level 3D projection.

Created look-up tables for trigonometric functions. Refactored sprite loading. Added sprites to bonus levels.

Enable sound directly after init, not only when playing music.

Updated scene playback with more animation attributes and types. Now playback ][ frames which is full screen frames. Two types of frames missing FF and RC frames. These are the only frame left that are used.

Store more than one background from animations. 
Store the related animation index for a scene page.
Updated constant naming for animations parts.

Add function def of sinf,cosf and tanf. Symbian is missing these functions in its math.h file, but should it be located some where else?

Added support for continue yes/no scene. added to extra controls yes_no (for extended config for ports), defaults to y, n keys.

Not all compilers allow pointer comparison with anything but the pointer type or NULL! Just wondering when the Level* level should be < 0? I think != NULL is the correct statement.Please correct if not!
