Dollar/$ in query per OData is incorrectly encoded

[steve-o]

This is still a continuing issue with Swagger as of June 2nd 2016, it is resolved in the editor (2.10.1) per case swagger-api/swagger-editor#308 but not the UI (2.1.4) and so overly inconvenient when defining OData queries with pagination or change tracking, for example:

"parameters": [
    {
        "name": "Prefer",
        "in": "header",
        "required": false,
        "type": "string",
        "description": "For paging request set to \"odata.maxpagesize=10\", where 10 is the maximum number of files to return in each response.  For change tracking set t
o \"odata.track-changes; odata.maxpagesize=10\"."
    },
    {
        "name": "$skiptoken",
        "in": "query",
        "required": false,
        "type": "string",
        "description": "For paging request, a token to refer to a previous request."
    },
    {
        "name": "$deltatoken",
        "in": "query",
        "required": false,
        "type": "string",
        "description": "For change tracking, a token to refer to a previous request."
    }
]

This case was recorded previously as #1469 but prematurely closed by that author.

@steve-o please open an issue in swagger-js so this can be addressed before next release.
