What's New
Added "external tool" support. Similar to Eclipse, this allows you to define and run external processes, and get their output in a docked window.
Improved "Tasks" support. The user can now define what words denote "tasks" in the options menu.
Improved ctrl+arrow key navigation in the text editor (now works like Eclipse) as well as word selection when double-clicking with the mouse.
Added an option to show EOL markers in the editor.
Fixed exception thrown when spell-checking plain text.
Code cleanup and simplification, especially of "plugin" architecture.
Fixed a handful of smaller bugs.
Updated translations: Turkish (Burak), Dutch (Roel), Brazilian Portuguese (Marcos), Spanish (Rafael), Arabic (Linostar), Simplified Chinese (Sunquan).
Added Polish translation (thanks Maciej!).
