v.2.19

• Fixed message preview window images loading when URL has https.
• Fixed IMDB leeching.
• Fixed few small leeching problems.
• Added automatic messages saving to .txt files inside "user/messages" folder by section. First time loading after update might take longer if you have a lot of messages (will try to save all).
• Added setting "Leech short description from IMDB." in "Options" -> "IMDB".
• Added setting "Automatically mark with color messages with extracted and replaced links" in "Options" -> "Messages".
• Improved multiple messages preview window. Messages are now displayed in the list (you can still use arrow keys to navigate). Windows loads much faster (almost instantly).
• Other small improvements and fixes.
