ShareX 11.3.0

What's new in this version:

- Using AppVeyor build server to compile and build ShareX setup/portable files and release them automatically without any user interaction that way it will increase security of our releases
- Added experimental setting to use ShareX region capture to annotate images instead of using Greenshot image editor (In "Task settings -> Advanced tab -> UseShareXForAnnotation")
- Added Uplea file uploader (by @osfancy)
- Added secondary screenshot path location option for situations where primary custom screenshot path is unavailable (In "Application settings -> Advanced tab -> CustomScreenshotsPath2")
- Added transparent button to color picker dialog
- Removed up1.ca file uploader because service is down now
- In image file dialog not allow non image file types to be selected
- Updated DreamObjects endpoint
- Returned SSH.NET library to previous version until buffer related issue fix is released

Region capture related changes:
- Added speech balloon drawing tool which works similar to text drawing tool but have moveable tail
- Added image drawing tool so now you can select image from file dialog
- Added support to paste image or text using Ctrl + V key
- Allow region capture right click menu to be closed by right clicking inside region capture window
- Using rounded cap for line/arrow drawing
- All region capture related tasks (screen color picker, ruler, screen record region selection etc.) will use currently configured region capture options such as magnifier, crosshair, snap size etc.
- In text drawing tool, rectangle will be automatically resized according to initial text size so no need to drag rectangle when adding text anymore
- Added corner radius setting to text drawing
- In text input window, pressing Ctrl + Enter will close window
- In text input window, if a non-existent font was selected, automatically default to Arial font
- Swapped Mouse wheel tool changing keybind with Ctrl + Mouse wheel magnifier zoom changing keybind, otherwise people can change tool accidentally; so Mouse wheel will only change magnifier size now which will be less problematic than changing tool accidentally
- Change pixel offset mode dynamically depending on pen size to draw line, rounded rectangle etc. aligned to exact pixels to avoid blurry lines
- Removed Region capture (Simple annotate) hotkey because now current region capture have all features of old region capture annotate window
