Fix HTML, CSS and JS leaking into conversation list preview. Bug 714317 When generating the preview, only the first 128 bytes of the first MIME part is fetched and used. If this part is text/html with a significant amount of embedded CSS, then there is a good chance the string passed to Geary.HTML::remove_html_tags() will be invalid, or be missing closing elements. Since that function uses regexes that require balanced tags to remove script and style blocks, then it was very possible that in these cases this method will miss removing these blocks. To solve this, remove_html_tags() is removed and its call sites are replaced by calls to Geary.HTML::html_to_text(), which has been tidyied up to produce more human-readable result. Add unit tests to cover new html_to_text functionality and its call sites. * src/engine/util/util-html.vala: Remove remove_html_tags(). Update html_to_text() to not just insert line breaks, but also insert spaces and alt text, and ignore tags like HEAD, SCRIPT and STYLE, as appropriate. Add an optional param to also allow skipping BLOCKQUOTE elements, which we don't want in the preview.

Tidy up unit test infrastructure and mock classes. * test/api/*.vala: Renamed files that contained mock objects to *-mock.vala, not *-test.vala. * test/testcase.vala: Renamed to test-case.vala for consistency, remove TestCase class from Gee package since that's really not true. Clean up code for consistency. * test/meson.build, test/CMakeLists.txt: Split TestCase compilation out into a separate test lib.

Fix MS mailers munging plain-text signatures in HTML body parts. Geary previously wrapped plain text sigs (i.e. those that did not contain any HTML elements) in a DIV styled to preserve whitespace. This is all perfectly fine, except that certain Microsoft products munged the email for presentation and destroy the whitespace present in the message body, causing the sig to be mis-rendered. This works around their shitty software by using BRs instead of the DIV, also escapes other control chars and sequential whitespace as well when using a plain text sig. It also stops trying to smart-escape quoted reply text, since we know it's going to be HTML from the conversation viewer, meaning smart escaping only needs to be used for sigs. See issue #29

I think we could do that!
Fix HTML, CSS and JS leaking into conversation list preview. Bug 714317 When generating the preview, only the first 128 bytes of the first MIME part is fetched and used. If this part is text/html with a significant amount of embedded CSS, then there is a good chance the string passed to Geary.HTML::remove_html_tags() will be invalid, or be missing closing elements. Since that function uses regexes that require balanced tags to remove script and style blocks, then it was very possible that in these cases this method will miss removing these blocks. To solve this, remove_html_tags() is removed and its call sites are replaced by calls to Geary.HTML::html_to_text(), which has been tidyied up to produce more human-readable result. Add unit tests to cover new html_to_text functionality and its call sites. * src/engine/util/util-html.vala: Remove remove_html_tags(). Update html_to_text() to not just insert line breaks, but also insert spaces and alt text, and ignore tags like HEAD, SCRIPT and STYLE, as appropriate. Add an optional param to also allow skipping BLOCKQUOTE elements, which we don't want in the preview.
