Doczom cde50c18ed Update to 0.2.0 version 
## Program interface
- Added the function ``` char* find_uri_args(CONNECT_DATA* session, char* key) ```
- Added the function ``` char* find_header(CONNECT_DATA* session, char* key) ```
- Fixed a bug in ``` Get_MIME_Type ```
- Added the function ``` void close_server(); ```

## Module interface
- The initialization function and the request processing function have been changed:

``` uint32_t stdcall httpd_init(IMPORT_DATA* import, char* cmdline) ```

```` void stdcall httpd_server(CONNECT_DATA* request_data, uint32_t pdata) ```

Added a module shutdown function for a specific uri:

``` void stdcall httpd_close(uint32_t pdata) ```

## Modules
- Added a module for testing parameter transmission during initialization

## Other
- Added a build script
- Added a single file for the program and modules with constants and structures
