More operators and general flexibility

This update adds more operators and increases general flexibility. This is the first official release of Rumor that is not in a pre-release state.

If you find Rumor useful, consider supporting development of this framework by becoming my patron. Development of this framework is only possible with the continued patronage of my patrons.

Added

• Added the ability to specify a clear for just dialog or just choices
• Added the default binding _choice, which returns the contents of the
  last chosen choice
• Added the -=, +=, /=, and *= assignment operators
• Added the <, <=, >, and >= comparison operators

Changed

• The OnClear event in RumorState has been changed to use a ClearType enum,
  which specifies if everything, just choices, or just dialog was cleared
• The Pause command will now wait for an advance if the time is less than or
  equal to 0
• Multiple methods of the same name can be binded as long as they have a
  different number of input parameters

More events and general bugfixes

Added

• Added an OnDialogAdd, OnDialogSet, and OnClear events to RumorState
• Added the Clear command
• Added an OnWaitForAdvance and OnWaitForChoose event to Rumor
• Added a Cancelled property to Rumor

Changed

• AutoAdvance is now a time instead of a toggle, which indicates the amount of
  time before the Rumor will attempt to automatically advance
• Bindings are now stored in the Rumor instead of the Scope

Fixed

• Fix null variables not handled properly in expressions
• Fix no boolean literals parsing in RumorCompiler
• Fix nodes not checking for null values
• Fix If conditional not checking for null values

Choose commands

The major feature addition in this release is the Choose command. You can read more about how it works in PR #11.

Added

• Added an AutoAdvance property to Rumor that causes it to automatically
  advance if possible
• Added Cancel and Finish methods to Rumor
• Added CancelCount and FinishCount properties to Rumor
• Added a Choose node
• Added the ability to use one-line comments

Changed

• Added SetupDefaultBindings convenience method to Rumor for common bindings
• Choice nodes no longer automatically wait for a choice at the end of a
  chain of choices. Instead, use the Choose node to wait for a choice

Better Rumor execution behaviour

Added

• Added a Running property to Rumor
• Added OnStart and OnFinish events to Rumor
• Added OnVarSet event to Scope

Changed

• Rumor.Run() will restart the script instead of throwing an exception if it
  is already running
• JumpToLabel and CallLabel are now exposed publicly, and work even if the
  Rumor has not been started yet
• Rumor constructors now provide a convenience method that takes a string
  directly
• You can now pass Rumor a scope to use

Removed

• The RumorCodeExample has been removed as it's potentially
  misleading/confusing

Initial release

The following actions are available in this initial release:

• Label - Specifies a location
• Say - Replaces the dialog in the current state
• Add - Appends text to the end of the dialog in the current state
• Choice - Adds a choice and all following choices to the current state
• Pause - Pauses execution for a short amount of time
• Jump - Modifies the stack so that execution will continue at the specified label
• Call - Pushes a new stack frame onto the stack with the children nodes from the specified label
• Return - Exits the current stack frame

You can also:

• Bind methods to a Rumor's scope
• Subscribe to events on each new node
