Stable release version 1.5

Quite a rushed and smaller release because of the plethora of problems with input found in the previous version. Sorry about that.

Here are the changes...

Added:

• Movement multipliers in code. Can be used to easily make the player faster/slower and jump higher.
• Camera force look.
• SetPosition, SetLocalPosition, and SetPositionAndRotation methods added to easily set the position.

Improvements:

• Eliminated garbage caused by string concatenation.

Changes:

• Removed all references to HertzLib update manager.

Fixes:

• Fixed not being able to use the old input manager.

The next update should be a lot better!
