I think formatting works properly now?

When boosting something, status contents are not stored in status
itself, but rather in the `status.reblog`. Since it'd be really awkward
to check for boosts too, I just decided to add separate `@property` that
returns either reblog or status itself, depending on the value of
`status.reblog`. That required a bit of tweaking. Also now we're using
ExtendedInterpolation, so you can do the `${tokens.telegram}` and add
separate section for your secrets.
TODO: add support for environment variables (maybe)

For those who's wondering how manual check for boost would look in the
template, here ya go :)

{% if status.reblog %}Boost from <a \
href="{{status.reblog.account.url}}">{{status.reblog.account.name}}</a>
{% if status.reblog.spoiler_text %}{{status.reblog.spoiler_text}}
<tg-spoiler>{% endif %}{{status.reblog.content_flathtml}}\
{% if status.reblog.spoiler_text %}</tg-spoiler>{% endif %}
{% else %}
{% if status.spoiler_text %}{{status.spoiler_text}}
<tg-spoiler>{% endif %}{{status.content_flathtml}}\
{% if status.spoiler_text %}</tg-spoiler>{% endif %}
{% endif %}

<a href="{{status.link}}">Link to post</a>

You asked for this :)
