v.3.5.0.23

This is a 3.5.0 Patch 1, containing few important fixes.

Editor:

• Fixed changing Audio Clip ID or deleting a clip could break sound links in view frames.
• Fixed importing an older version project during the same editor session, in which one game was
  already opened, could assign previous game's GameFileName property to the next one.
• Fixed some fonts may be not drawn on GUI preview after any font with lower ID was modified.
• Fixed Pause and Stop buttons were enabled when first opening an audio clip preview, and clicking
  these could lead to a crash.
• Fixed a potential crash during audio clip preview (related to irrKlang .NET library we use).
• Fixed a potential resource leak in the sprite preview.

Engine:

• Fixed IsKeyPressed script function returning values other than 0 or 1 (broke some scripts).
• Fixed grey-out effect over disabled GUI controls was drawn at the wrong coordinates.
