minicode (variant of BBCode) - easy editing HTML

Introduction:

minicode is a lightweight markup language for miniroll easy editing, learn from BBCode.
The tags are indicated by square brackets [ ] surrounding a keyword.
It is designed for Blog, thus let through unsafe HTML like <script>.

Syntax:

The minicode cannot nest:
```
[url]http://goo.gl/[/url] OK
[b][url]http://goo.gl/[/url][/b] This expression is ERROR!!!
```
Because nest will be complex. In this situation, you can use HTML directly or use [lead_define].
Difference between minicode and BBCode:
```
[url]http://php.net/docs.php[PHP Manual[/url]
[color]#B22222]FireBrick[/color]
```
Note the tag option is close to the [tag] with a sigle square bracket:
[tag]option]...[/tag], or [tag]...[option[/tag]
Position of tag option depends on the implemented HTML sentence.
Do not add newline in the tag option of a minicode, it will be failed.
