Summary:
This patch defines the way style property will work at canvas_text object
1- Changing canvas_text style property using Font/Format/Style interfaces or with efl_canvas_text style property are the same.
Example:
```
efl_text_font_set(tb, "Arial", 30);
//is same as
efl_canvas_text_style_set(tb, "font=Arial font_size=30");
//which means calling
char * font;
int size;
int font_size;
efl_text_font_get(tb, &font, &size);
// calling this after any of the top two functions will return same result
```
2- style_get_property
Will return string that contains full details about all the current applied style at canvas_text level.
3- style_set_property
Will only override passed styles and leave everything else as it is
```
efl_canvas_text_style_set(tb, "font=Arial"); // overrider font name to Arial and leave everthing else
efl_canvas_text_style_set(tb, "font_size=30"); // overrider font size to 30 and leave everthing else (font name will stay arial)
```
