Pretty URLs plugin: Change wording

[azett]

Proposed by Detlef on the forum:

May be I can propose a change in wording for the pretty-urls config:

This editor lets you edit your /flapress/base/root/.htaccess

Directly afterwards, if not writeble:

At the moment either /flatpress/base/root or /flapress/base/root/.htaccess or both aren't writable for the webserver. You either can give write permission or create .htaccess like below manually and copy or upload to flatpress/base/root .

Then follows the editor window.

And /flatpress/base/root should of course show the path for the current installation.
