Support for PUT/DELETE http methods

[GoogleCodeExporter]

Mongoose requires setting PUT_DELETE_PASSWORDS_FILE option (.htpasswd file with 
username/password), and later when performing PUT/DELETE request these 
credentials must be included in headers.

A new option in settings.json "put_delete_password_file" with two possible 
values:
a) A path to "/.htpasswd" file
b) Value of "no-password-file-required" - this would require modification in 
mongoose.c so that password is not required for PUT/DELETE requests.

An example .htpasswd file, from Mongoose UserManual:

    ### global\_auth\_file
    Path to a global passwords file, either full path or relative to the current
    working directory. If set, per-directory `.htpasswd` files are ignored,
    and all requests are authorised against that file.

    The file has to include the realm set through `authentication_domain` and the password in digest format:

        user:realm:digest
        test:test.com:ce0220efc2dd2fad6185e1f1af5a4327

    (e.g. use [this generator](http://www.askapache.com/online-tools/htpasswd-generator))
