For Bug

Hexo does not support Incremental Build.

I found that hexo will still render files even there is no file modified.
It eventually caused the slow hexo build.

➜ blog2$ git:(master) ✗hexo g
INFO  Start processing
INFO  Files loaded in 3.29 s
INFO  0 files generated in 1.38 min

$ hexo --debug g
......

07:39:30.907 DEBUG Rendering post: c/ops-fabric/index.html
07:39:31.140 DEBUG Rendering post: c/ops-dd/index.html

For feature request

Let hexo support incremental build.
