Introduced a new resource compiler script kiwix-compile-i18n that
processes i18n string data stored in JSON files and generates sorted C++
tables of string keys and values for all languages.
Mustache templating system is a bit simpler than ctpp2 and ctpp2 is no
more maintained (see #189).
We are moving to the kainjow's Mustache project
(https://github.com/kainjow/Mustache).
It simplify a lot our system has it is header only and we don't have to
precompile the template.
Fix#21
- No more dependency to reswrap binary (everything is done in python)
- Resource strings can be directly accessed.
As side effect, it add a check at compilation if the resource is
declared and compiled in the binary.
- The resource content can be overwritten at runtime with a env variable.
There is also few clean in the static as some files shoul be in the tools
directory.
The compile_resource script is install to let other project use it.
