Add `reStructuredText` support in templates This release adds `reStructuredText` code to the `annotate_file_content` template. (All other templates are markup language agnostic). To create a new ReStructuredText note invoke Tp-Note with: ```sh TPNOTE_EXTENSION_DEFAULT=rst tpnote ``` To make ReStructuredText the default markup language for all future new notes, write a configuration file '`~/.config/tpnote/tpnote.toml`' with the following content: ```toml [base_scheme.filename] extension_default="rst" ``` Other new features: * Make `exporter_highlighting_css` configurable * Make `viewer_highlighting_css` configurable Some minor bug fixes shipped with this release: * errorpage: display correct path to browsed doc * Rst renderer: always `trim()` input
