Audio:dumpSoundArchive() : I've added an error message and dump progress info
Replaced tab identations with 2 space identations
Fix nesting of conditions in Humanoid:afterLoad

Before this fix the condition: [ if old < 77 then self.has_vomitted = 0 end ] was not checked for saved games newer than 41 because this condition was nested within the: [ if old < 42 then ] condition.
Utility:tables_length() unlike # this can return the length of any table.

#table_name is only suitable for use with arrays of one contiguous part
without nil values:

This function is used by the audio code I've made for my WIP hell deaths
implementation.
Changed its name & made its for loop more readable
Baldness bloaty head death fix: I've made them die with hair instead
I've add an extra if condition

I've added this to make sure they would have a bloaty head if their head wasn't changed, in case they die after being treated.
Removed the condition: "humanoid.layers[0] == 12"

I removed this so that both treated (with head 14) and untreated bald patients (with head 12) will be given the black haired standard male patient's head when they die because their bald head and treated head aren't supported by the death animations.
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)
Update idle_spawn.lua
Update idle_spawn.lua
I've made the idle action queuing line shorter
Patient:isMalePatient()

This new function is required by die.lua:action_die_start for hell
deaths because female patients can't go to hell.
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."
Style and grammar fixes to CONTRIBUTING.txt
.gitIgnore: added VS Express user config file (*.suo)

CorsixTH.v12.suo is generated by Visual Studio Express 2013 to store a
user's configuration.
I've finished the continue button.

Added Polish error message for no_games_to_contine.

Added Russian error message for no_games_to_contine.
Made this button's Polish label shorter

Load latest game -> Return to game

I thin the Russian label my Russian friend gave me is fine.
I've moved the settings button so that only the exit button will  be seperated from the other buttons.
