* renamed .htaccess to .htaccess-dist and ignored .htaccess afterwards. This
allows local changes to it without having a dirty checkout directory.

Signed-off-by: Roland Häder <roland@mxchange.org>

* Some fixes:
- removed non-neutral words
- added examples for Linux/Windows

* Better documentation and added note about **not** renaming the file.

+### Prepare .htaccess file
+
+Copy .htaccess-dist to .htaccess (be careful under Windows) to have working mod-rewrite again. If you have installed Friendica into a sub directory, like /friendica/ set this path in RewriteBase accordingly.
+
+Example:
+
+    cp .htacces-dist .htaccess
+
+*Note*: Do **not** rename the .htaccess-dist file as it is tracked by GIT and renaming will cause a dirty working directory.
