ignore configs, htaccess mod_rewrite check

Proposal changes for issue #24

Not sure which branch should be the target. I specified MASTER branch.

These configuration files will be deleted after update and putted to GIT ignore list
* config/config.yml
* config/database.yml

New configuration template files were added
* config/config.base.yml
* config/database.base.yml

It is highly recommended to backup working configs before apply this update.

Also there are minor change in .htaccess
