condformat 0.9.0

Breaking changes

The lazyeval API deprecated on condformat 0.6 has been dropped, only the tidy evaluation API remains. This fixes dplyr 1.0.0 test failures.

space is ignored and deprecated in rule_fill_gradient and rule_fill_gradient2, following recent changes in the scales package. Please remove it if you are using it, as it will be removed in a future version

rule_fill_bar (HTML, for now)
rule_text_bold (HTML, PDF)
rule_text_color (HTML, PDF)
theme_htmlWidget (HTML) Customize the number of entries and the widget size.
theme_kable (PDF) pass options to kable
theme_caption (HTML, PDF) Set a caption.
condformat2grob: Engine to render tables as graphics
Shiny: renderCondformat works with async promises (if htmlwidgets 1.3 is available)

Deprecate: theme_htmlTable now only accepts arguments to be passed to htmlTable::htmlTable. Before, it could also be used to accept number_of_entries, width, height… to customize the widget appearance. For that use case, please use theme_htmlWidget instead.
Deprecate: condformat2widget will not accept arguments to customize the appearance of the widget. Use theme_htmlWidget instead.

Replace dependency: Use grDevices instead of gplots
Depend on knitr 1.18: slidy and other rmarkdown formats are properly detected (#13)
Drop rJava from suggests (xlsx fix released)
Bump rlang dependency (parse_quosure -> parse_expr) (#18, Thanks to @lionel- for the advice and code review!)
Internal: More modular code. CSS tags to LaTeX conversion is based on S3 methods so new rules don’t need to touch the code for LaTeX export.

Add a new condformat API, that is based on tidy evaluation principles and leverages on rlang and tidyselect. The old API is still fully functional but deprecated.
Add a rule_css to let the user specify arbitrary CSS fields. For this rule there is no support for PDF or Excel output.
Improve condformat2excel to export to a specific Excel sheet (#11)
Fix condformat2latex and add regression test (#9)
Fix rescale and rescale_mid calls (recent scales use a S3 generic, so we need to import it)

Fix tibble formatting issues, causing package malfunction.
Bugfix: theme_htmlTable() now accepts the css.cell argument (thanks to 鱼飞灰 for reporting it)
Require latest htmlTable. Improve/fix printing of condformat

Shiny support: Add condformatOutput and renderCondformat. Closes #3.
- Use pagination in shiny if recent enough htmlTable package is installed.
PDF support: Fix extra NULL when printing. Closes #4.
Demote xlsx (and rJava) to Suggests.
Fix standard evaluation functions, they now use formulas. See the examples (Reported in #5).
Fix Excel export (fixed in 80440ecfd16fb74e3e0aa4c6ebc623ad2ae74b15, reported in #7)
