Freeciv build in Docker with fix to year notation

 I don't get BCE/CE and why this is becoming the fashionable change to dates as of late.  Anyway, I thought, why not recompile with AD/BC returned.  Turns out that I don't understand translations but I found a quick and dirty hack.

Dockerfile:

FROM ubuntu:18.04

RUN cp /etc/apt/sources.list /etc/apt/sources.list~
RUN sed -Ei 's/^# deb-src /deb-src /' /etc/apt/sources.list
RUN apt-get -y update
RUN apt-get -y build-dep freeciv
RUN apt-get -y install build-essential fakeroot devscripts
RUN mkdir /src
WORKDIR /src
RUN apt-get -y source freeciv
WORKDIR /src/freeciv-2.5.10
#RUN tail -F /dev/null
RUN find . \( -name \*.po -o -name \*.ruleset -o -name \*.mo -o -name \*.txt \) -exec sed -i -r -e's/\bBCE\b/BC /g' {} \;
RUN find . \( -name \*.po -o -name \*.ruleset -o -name \*.mo -o -name \*.txt \) -exec sed -i -r -e's/\bCE\b/AD /g' {} \;
