Add building time

[HelloWuJiaYi]

增加了一个小小的功能，在页面的底部显示博客站点的建立时间。
只需按格式更改主题配置文件的 Building_time 。

Add site creation time at the bottom of the page.
Modify the topic configuration file"Building_time".
Time keeps accumulating.

Need to:

1. Add localization.
2. Add switch condition option.
3. Move this code from footer to separate file.

[HelloWuJiaYi]

Hello, I've moved the code from the footer to a separate file, but I'm not sure what it means to add localization？

This is the first time I submitted the code, not very clear about the process. Thanks very much。

@HelloWuJiaYi your code provide only Chinese and English language. NexT support multilanguage select, this mean if user chose Russian language, he will see Chinese letters with your plugin enabled. Need to add support for all languages, not only for Chinese.

In your code:

{% if config.language == "zh-Hans" %}  {{ "建立时间 : " }}
{% else %} {{ "Building Time : " }}

And if config Ru language? If De? If any other ≈10 languages? Need to add support for all languages, dynamic support. Something like:

-{% if config.language == "zh-Hans" %}  {{ "建立时间 : " }}
-{% else %} {{ "Building Time : " }}
+{{ "{{ __('post.building_time') }}" }}

And in languages/default.yml:

post:
  building_time: Building Time

And in other languages other translates.
For more information u can see layout/_macro/post.swig file for examples multilanguage support.

[HelloWuJiaYi]

Well, thank you very much. I'll change the code.
