Fixes replacement of table prefixes

If a package, that is no application, requires an application (in WCF 1, this would have been a plugin), only the `wcf1_` prefix is replaced, thus altering existing application tables or creating new application tables isn't possible.

This commit now replaces app1_ with app{WCF_N}_ for all installed applications.

Grammatical corrections

I've corrected two minor mistakes in line 79 (orthography)and 81 (missing suffix).
Stylistic corrections

I've changed within line 183 three minor instances referring to grammatical and stylistic aspects. Basically to let it sound "more natural"

l.23 correction of the wrong preposition.
Sentence adjustments

Line 60/62/666/69/72: rewritten the compound (cronjob)and changed the verb due to the technical context.

I'd suggest "concerning" in line 104, due to reasons of style. That means, it sounds more professional.
Lexeme corrections

I've changed these things:
line 104: prepositional change
line 115: replacing a rather informal term into a more formal one. Moreover, I've added a plural-suffix and the latter sentence due to style.
line 126: inserting a comma and changing a preposition
Update option.tpl

Added two new template events
Spelling corrections and translations

1. I've corrected the spelling in these lines:
line 175 (look up)
line 190 (multi-)

2. I've translated the missing phrases in the following lines:
line 173 ("Template" would be also appropriate, but I think this lexeme is already used in the WCF context)
line 200-206

3. I've corrected the spelling in line 190 (no capital letter)and changed the preposition due to the meaning.
Style adjustments

Applied changes:
line 213: I've changed a verb and preposition;
line 216: inserting a comparative particle due to stylistic reasons as well as changing two verbs;
line 220: I've inserted two missing commas, corrected a spelling and adjusted the sentence due to syntactic reasons.
Prepositional suggestion

I'd suggest to insert in line 244 and line 264 "to" in order to elucidate the relation between the subject and object.
Word change

I've changed the adjective in line 281 into a verb, due to the "natural flow" of the sentence. 

Furthermore I have a question concerning your chosen noun in line 278, namely "weight factor". What do you want to state with it, respectively, what kind of context are we talking about?
