[PATCH] Update wall_builder and add wall_demo random map

[FeXoR]

Updated rmgen lib wall_builder.js:

• Updated to new object placement in random maps
• Updated to new walls and towers of celt, hele and iber
• Tidied and documented code
• Added linear and circular wall placement functions

Fix random map fortress:

• Updated to the new method that fixes the poor placement since object placement changed

Added wall_demo random map as an code example

I still don't know what component to choose...

Further changes:

• Fixed random map deep_forest that contained unused fortress placement (removed it)
• Added placeCustomFortress that doesn't depend on fortressTypes associative array
• Changed fortress placement in random map fortress.js to the new placement method
• Added 'undefined' entity support for linear/circular walls (needed for entries)
• Added documentation and brought it up to date
• Added some checks and warnings

You'r to slow ;)

Updated patch to 11430

• Added 'others' to wall styles including fences, columns, benches, tables, flags, ...
• Fixed a minor bug that raises warnings when the last wall elements entity was 'undefined'
• Added and clarify documentation

I'm to impatient x)

Fixed the house placement for random map 'fortress'. Playtested and all get 50 population cap at start but Celts. Celts get 54 but I think it's better then 49 with one house less. Celtic fortresses only add 12 instead of 15 population cap anyway. And it was like that before. The 4 additional population cap comes from the barracks. THX much, Leper, for finding this!

The game was updated many times but AFAIK none of the files I edited. But just to make sure everything works fine with the update I added any single file changed as it should look after the patch. This ticked replaces Ticket #1288. Sorry for the 'double ticket'.

Patch for wall_builder.js, fortress.js, wall_demo.js, wall_demo.json, deep_forest.js and deep_forest.json

Some comments:

Move the comments after the function definition and before the opening brace in front of the function. Remove (or start to) the unneeded semi-colons.

wall_builder.js
You have some strange symbols (in the comments with the degree sign).
I'd replace the definitions in WallElement and other functions with ternary operators as in this.angle = (angle !== undefined) ? angle : 0*PI;.
line 293 typo 'exsists'
You should use === to check if something is undefined (as noted in our coding conventions).

That are just some things I noticed while reading some of the code.

[FeXoR]

• Removed all semicolons after function, for, while, if and else
• Moved the comments from between function definition and opening brackets befor the function definition
• Separated different parts of documentation more clearly
• Removed the angles in degree from documentation
• Removed the type 'exsists' -> 'exists'
• Changed ' == undefined' -> ' === undefined'

Changed to ternary operators or something like 'angle = (angle

0)'

NOTE: A patch was added concerning most random maps while I edited including fortress.js
