Allow inline links like "test?param[]=value"

Tested with the following textile snippets:

Syntax that should work still after the patch:

    Try it out on "github":http://github.com.

    ...blah blah (for more details look on "github":http://github.com) blah blah...

    ...blah blah [for more details look on "github":http://github.com] blah blah...

    ...blah blah[^["on github":http://github.com]^] blah...

    ...blah blah ^["on github":http://github.com]^ blah...

Syntax that did not work before:

    "my link":http://github.com?param[]=value

    In a sentence "my link":http://github.com?param[]=value.

    In a sentence "my link":http://github.com?param[].

    ...blah blah ^["on github":http://github.com?param[]]^ blah...
