String errors in frisian helptexts

[Benedikt Straub]

The helptext for frisian bread says:

> Bread is made out of barley and water and is used in the taverns and drinking halls to prepare rations. It is also consumed by training soldiers.

Drinking halls can´t use normal bread though, so the text needs to be corrected.

[Benedikt Straub (nordfriese)]

And the need for coal for bricks is missing from the helptexts both for coal and bricks.

The felling ax refers only to the "lumberjack", though he is called "woodcutter" for atl and fri.

The fire tongs always refer to the "smelting works", which is called "furnace" for fri.

[Benedikt Straub (nordfriese)]

Fruit helptext:
> Fruit are berries gathered from berry bushes by a fruit collector. They are used for rations and meals.
"Meals" is wrong, and aqua farms are missing.

The gold helptext always refers to the "smelting works", which is called "furnace" for fri.

[Benedikt Straub (nordfriese)]

Same as in #4 for gold ore

[Benedikt Straub (nordfriese)]

And for iron and iron ore as well

[Benedikt Straub (nordfriese)]

Mead:
> Mead is produced by mead breweries and used in drinking halls for producing meals. Soldiers drink mead during advanced training.
Incorrect, it´s used only by soldiers (meals need normal beer).

[Benedikt Straub (nordfriese)]

Same as in #7 for the Mead Brewery
