enhance markdown editing

[laoshaw]

markdown is getting even more common these days it would be nice that geany can make itself a first class markdown editor. The "urgent" features I would request:

1. When adding a list, a return key should automatically make next line ready for next line in the list, now I have to type first two letters with each list line, e,g. "* my line", the "* " part should be automatically added by geany.

2. select a few lines and change them to a list easily together, like what ctrl+I/U does for indent

3. when type headlines they should be bold as what bold already does, now #, ## headlines are shown as regular text

4. select some text then use keybinding to make it bold or italic, e.g. Ctrl+B(bold), ctrl+I(italic) , or just type ** , * it can surround the selected text, currently I can only do this with back tick sign automatically, e.g. the `my code line`

with above features, geany will become one of the best markdown editor, that alone is enough for its wider usage

Those are the sorts of things you can add to a plugin for markdown.

I actually feel this could be part of the core function of geany, is there a markdoen plugin for this? there is a so-called markdown plugin but it is just for previewing as far as I can tell, not for editing, the markdown editing is part of geany instead of a plugin, or I must be missing something basic(not a geany developer)

Functionality that is specific to a filetype should not be part of core, not everyone wants every language special functions cluttering up their editor. Plugins is the way all editors do it these days, Atom, Emacs, Eclipse etc

One thing that would be really cool is if it was possible to apply code syntax highlight on the fly! =)

for example:

```c
int main() {}
```

would show:

```c
int main() {}

Today Geany already shows italic bold. Highlight code would be awesome.
