dictextension dict

Use native EOL to make it easier to edit in notepad.

Set the version to 0.9.0 for a formal release.

Use 6 instead of 8 when looking up HTML content on dict.bibleonline.ru.
This additionally tests the screen limit on the resize-window-to-content, as "6" has very wide content that is intented to wrap.

Limit the window size to the size of the screen.
This prevents very long definitions from being being rendered off-screen.
This was added because very long HTML content can be written that is intended to wrap to the size of the window and so sizing the window to fit the content is not appropriate.

Refactoring: move shared logic into createHtmlDefinition() to avoid code duplication

Fix a few copy&paste errors where a MIME header was added where it shouldn't have been.

Use CSS instead of HTML and explicit line breaks to format the definitions.
This makes the logic simpler and is "more correct" in the sense that HTML should provide the document and CSS should style it.

Also, let HTML definitions style themselves, instead of enclosing them in a <CODE><PRE> equivalent.

Fix a bug where the newline from the end of the MIME header was included in the definition.

Add a regression test for when one definition has unknown MIME content, but another has a supported MIME content.

Fix a UI weirdness where, if the DICT server responded with definitions which all included unknown MIME types, then an empty window would be shown. Now it shows a "no definitions found", which is better, even if it's still not perfect.
