markdown 每日笔记

Markdown don't allow space in the filenames. So encode to `%20` to replace the space in the filenames.

e.g. 

`([ontology](2.1 Ontologies.md))`

should be

`([ontology](2.1%20Ontologies.md))`

For example, you have a repo like the following:

``` html
project/
    text.md
    subpro/
       subtext.md
       subsubpro/
           subsubtext.md
       subsubpro2/
           subsubtext2.md
```
* The relative link to `subtext.md` in `text.md` might look like this:

`[this subtext](subpro/subtext.md)`
* The relative link to `subsubtext.md` in `text.md` might look like this:

`[this subsubtext](subpro/subsubpro/subsubtext.md)`
* The relative link to `subtext.md` in `subsubtext.md` might look like this:

`[this subtext](../subtext.md)`
* The relative link to `subsubtext2.md` in `subsubtext.md` might look like this:

`[this subsubtext2](../subsubpro2/subsubtext2.md)`
* The relative link to text.md in subsubtext.md might look like this:

`[this text](../../text.md)`
