Patient:isMalePatient()

This new function is required by die.lua:action_die_start for hell
deaths because female patients can't go to hell.
New humanoid action: idle_spawn

The existing spawn action requires spawned humanoids to walk to a tile
after they've spawned, where as this new spawn action doesn't require
this so a humanoid can spawn on a tile and then stand idle on it.

This is how the Grim Reaper spawns in TH, standing idle for a few
seconds before walking to a lava hole. This is why I created this action
and it can play the Grim Reaper's spawn animation and sound effect.

This action's fields:
* point (mandatory):  {x, y, direction}  Where the humanoid will spawn.
* spawn_animation (optional)
* spawn_sound (optional)
* Idle action's fields:  count (optional), loop_callback (optional)

I've made the idle action queuing line shorter

Add documentation about issue templates

Mailed the GitHub guys about this and they said that it is currently not possible to let bug reporters fill this in automaticly, as you could with Google Code, but they will might do this in the future. So, this issue is a kind of workaround till GitHub fully supports issue templates.
They said the following:

"Adding an issue template is not possible currently, but we might add it in the future. Thanks for the suggestion, I'll add it to the Feature Request List so the team can see it.

In the meantime, you could add an issue template to your repository's CONTRIBUTING.md file, which is linked whenever someone creates a new issue or pull request."
