Fixes

• Loading saved games is working when the file doesn't has data for the main types: characters, inventory items or dialogs.
• Creating dialogue lines (for E.run([])) with wrong character names doesn't break the game.
• Creating dialogue lines with empty emotions doesn't break the game.
• DialogText's ContinueIcon now is set to modulate.a = 0.0 instead of 0.5 (this was for testing purpouses).
• DialogText animation speeds were not working because the method to count the total number of characters in the line was returning 0.
• Cursor doesn't show the clock icon when a PopochiuDialog is active.

New things

• Added properties times_clicked and times_right_clicked to PopochiuClickable.
• Added methods disable_input() and enable_input() to PopochiuClickable.
• Created class for PopochiuDialogOption.
