change default patch/diff colours to magenta and cyan red/green is not a great choice for diff colours: it's a bad combo for (some) colour-blind people, and they may also carry an implicit meaning of 'good' and 'bad', or 'ok' and 'not ok'. Instead, just like tog and gotwebd, use a combo of purple and cyan, which was choosen by a colour-blind user (I'm told).

support gopher urls for search; document default-search-engine

add cmd_search to search using a search engine This adds a new command `search', bound by default to `s', that prompts for a query and loads and consult the ``oracle'' (the search engine) using default_search_engine (which will be made customizable.) It also temporarly supports only gemini URLs. Feature requested by -fab-, thanks!

some headers cleanup try to not include headers from headers, and remove some redundant include. This helps in modularizing the codebase and also helps during incremental compilations.

include cmd.h only where it is really needed

add default-protocol knob So that now one can decide to assume a finger:// or gopher:// protocol instead of gemini:// for load-url.

simplify if/elseif/else

add boolean variables The 'if zero/nonzero then...' is a bit annoying. Add proper booleans to the grammar of the config and use them when appropriate. Makes the description and the review of configuration files easier. This means that the old set olivetti-mode = 1 can now be written as set olivetti-mode = true Compatibility with the previous integer values will be kept for a while.

sort vars

add the up, root and home commands These navigates respectively one level up in the path hierarchy, to the root directory and to the "home". The home is considered to be the first path component in the form of ~username. `home' is yet to be implemented.

add load-url-use-heuristic knob This is still WIP and may change before the next release. It could be worthwile to resolve the URLs in load-url using the current page as base, so that while browsing <gemini://a.org/b/c>, using load-url to go to "/" would load <gemini://a.org/> instead of <file:///>. The new option `load-url-use-heuristic', if unset, provides exactly this behaviour. It is still a bit rough to use, as for e.g. loading <d.net> would now yield <gemini://a.org/b/d.net> instead of <gemini://d.net>. Will need more work in-tree, but for now add it so we can reason about it. See github issue #10
