MetaGer-Help Correction of misspellings and some completions

help-de and help-en

****Spelling: ****

• Settings/Note: "intem" --> "item"
• Search Filters: "xou" --> "you"

Content:

• Settings/Blacklist:"You can filter out not only search engines, but also special domains." --> "You can filter out domains here." (The search engines have another, own section.) Schreibt man hier "are having"?
• Search functions: "Exclude single words" --> "Exclude single words (affects the description of a result)"
• Search functions: "Exclude URLs" --> "Exclude URLs (affects the headline of a result)" These two sections should be put together.....
• !bangs : "FAQ"-hyperlink has to be deleted; no ressource
• Assoziator: "Our privacy policy is in place." better?: "Our privacy policy applies here as well"
• help (en) title is german
• Add MetaGer: "https://metager.de/meta/meta.ger3?eingabe=%s" --> "https://metager.org/meta/meta.ger3?eingabe=%s"
• Add MetaGer: line spacing is wrong (last line)
• Android app: Change hyperlink: "https://play.google.com/store/apps/details?id=de.metager.metagerapp" ---> https://metager.org/app to have the F-Droid link too.

Other:

• Help startpage: not enough space between footer and content
