luci(-ssl)-nginx: depend on luci-app-opkg

Commit 391e82d6a3 in 2018 added luci-app-opkg dependency to
the 'luci' collection and its derivatives, but as nginx collections
do not depend on main 'luci', they did not get the intended change.

luci-app-statistics: modify default amount of data items in RRD

Increase the default number of data items in the RRD database
from 100 to 144. That leads to better matching summarising/averaging
moments between day & week and week & month at the averaging intervals:
30sec, 10min, 70 min, 5h10min, 2d13h

Previous 100 led too easily to situations, where the longer period's
more scarce data gets selected for displaying in the graph. That could
happen if the longer period's last data point was stored more recently
than the last data item in the originally required period.
(E.g. if the last "week data item" was more recent than the last
"day data item", the week data was used for the day chart.)

(Note: this change only applies in a live router if the RRD database is
empty. E.g after reboot or after emptying the RRD database dir.)

luci-base: add support for plural translations and contexts in Lua api

 - Introduce a new luci.template.parser.ntranslate() function which
   takes a count, a singular and a plural translation string as well
   as an optional context argument and returns the appropriate,
   language specific plural translation.

 - Introduce an optional translation context argument in the existing
   luci.template.parser.translate() function

 - Support translation contexts in LuCI template directives.
   Translation messages are split on the first unescaped pipe
   character and the reamining string after the pipe is treated
   as context.

Examples:

 - `string.format(p.ntranslate(n, "1 apple", "%d apples"), n)` will
   return an appropriate plural translation for the given amount.

 - `translate("Load", "The system load")` will return an appropiate
   translation for `Load`, using `The system load` as disambiguation
   context (a `msgctxt` directive in *.po files).

 - Likewise `<%:Load|The system load%>` will translate the word
   `Load` while using the remainder of the string as context.

 - To use pipes in translations strings literally, they must be
   escaped: `<%:Use the "\|" character%>` will translate the literal
   string `Use the "|" character`.

 - Only record section deletions when the section to be removed actually
   existed in the original config or when it was staged for creation
   earlier. This avoids stray ubus not found exception when saving.
