Added web/main/IH/db/

web/main/index.php: Updated fragment redirect for new dotpath format (using ? instead of a relative path)

web/main/index.php: Updated path templates for new dotpath format (using ? instead of /)

web/main/**/.htaccess: Support dotpaths in the query string instead of in the path, so that non-dotpath paths don't need to be suffixed with / to prevent their filenames from being interpreted as dotpaths. Putting dotpaths in the query string still requires only one character between the host and the path, but it's ? instead of / . ? is in many ways more natural, because the dotpath is a non-filesystem string to be parsed rather than something that's already a filesystem path. This change also avoids the need to strip trailing /s in many RewriteRules, because the dotpath mechanism is no longer appending them.

Added web/main/dotpath.php, which parses any dotpath in the query string

web/main/util.php: Added coalesce()

web/main/svn*: Fixed symlinks to use .redmine instead of Redmine

web/main/IH/.htaccess: Fixed whitespace

web/main/IH/.htaccess: RewriteRule: Fixed bug where need to \-escape % because it's a special character in the replacement string (it references a regexp group matched by the last RewriteCond)

Removed web/main/Redmine symlink so that it isn't listed in the directory listing as a visible (non-hidden) file. (There is already a .redmine symlink which matches all case variations via web/main/.htaccess logic.)
