remove Request::post_tab and add Request::http_status

Instead of Reqest::post_tab we use now Request::post_in (pt::Space).

Request::http_status will be used instead Request::status,
but at the moment is not changed in all places.
Request::status has been marked as depracated.

While here:
- Check for root dir in App and not in FunctionParser,
let FunctionParser only log the root dir.
- Read post variables after parsing url parameters,
this allows winix functions to set limits
for post input.
- Set limits when parsing input json format, new
options added to config: post_max_object_items, post_max_table_items,
post_max_all_items, post_max_nested_objects.
There are similar options in each winix function (they are in
FunctionBase).
- Some refactoring in App.
- Add config option: log_whole_http_post if true
then the whole parsed post input is logged.
- Add config option: post_json_max - max length of input stream
for parsing json.
- Add config option: templates_request_status, default request_status.html
this is an ezc template used as [content] when the request status
is not 200_ok.
- Fix: Sort winix function didn't show items to sort (fix and do some
refactoring as well)
- Properly sort items in: ImgCrop, Ls, Sort, Upload
- Remove ezc templates: err_404.html, err_per_denied.html - now
request_status.html is used.
