Previously plugins could declare js_dependencies and css_dependencies
which in theory would then be embedded in the page by themes.
Practically this does not make sense when you have multiple themes
since the JS & CSS needs to be written with a specific theme in mind
in order to support it.
Which is also why js_dependencies and css_dependencies was actually only
used by the Oscar theme and ignored by the Simple theme because the
Simple theme doesn't bundle jQuery and has a slightly different page
markup.
This commit removes this broken feature and also moves the *.js files in
searx/static/plugins/js/ to searx/static/themes/oscar/src/js/plugins
(where they actually belong).
The oscar-specific CSS is now simply injected via the oscar-specific JS.
Fixes#769.
This makes it easier to separately handle search and index requests
from a web server or from a reverse proxy.
If a request to index contains a query, a permanent redirect HTTP response
is returned. This should give some level of backwards compatibility
for users that have set a searx instance in their browser's search bar.
Infinite scroll adds a `hr` tag to split up the sections loaded by it.
The vim bindings `j` and `k`, which jump to the next and previous result
respectively, search for a **direct** sibling with the class `result`.
With the `hr` between results a direct sibling cannot be found. To fix
this we remove the restriction of it having to be a direct sibling.
This improves the user experience by loading in the next entries shortly before him getting to the bottom. It makes the scrolling more smooth without a break in between.
It also fixes an error on my browser that scrolling never hits the defined number. When I debugged it I hit `.scrolltop` of 1092.5 and the `doc.height - win.height` of 1093, so the condition was never true.
