bump crengine: more than 64 styles, table layout fixes (#1208)

Includes:
- TextLang: German: loosen quotation marks handling
- Fonts: add LVFontManager::getFontFileNameAndFaceIndex()
- fb2.css: avoid break before footnote links
- FlowState: fix possible wrong baseline with nested inline-table
- Tables: fix possible layout issues with rowspan
- Table cells: minor refactoring of baseline handling
- getRenderedWidths(): better estimate table width
- lvstyles: allow for more than 64 styles

cre.cpp: add getFontFaceFilenameAndFaceIndex().
ffi/freetype.lua: add optional 'faceindex" parameter
to FT.newFace() so we can request a font other than
the first one from font collections (.ttc).
