Remove extraneous slash. This extra slash was preventing the file being displayed by DokuWiki. (apologies for the two pulls instead of one)

Remove extraneous slash

Previously only the path for the configured template was returned and
the parameter was ignored.

Removed extraneous whitespace to eliminate errors reported by the
Squiz.WhiteSpace.SuperfluousWhitespace sniff.

Fix violations for the following sniff
DokuWiki.Functions.OpeningFunctionBrace

Also removed an extraneous semicolon.

Fix violations for Squiz.Commenting.DocCommentAlignment.SpaceBeforeTag

Conflicts:
	inc/parser/xhtml.php

Fix violations for Generic.PHP.LowerCaseConstant.Found

Michael Hamann commented in pull request #306 that phpseclib has not
been adopted by the DokuWiki project. Therefore, the changes made to
reduce the CodeSniffer violations should be reverted and the local copy
of phpseclib should be excluded from CS checks. This commit reverts the
previous changes and adds the appropriate exclusion rule.

Change indentation to ensure code confirms to CodeSniffer rules.

Remove whitespace from end of lines to reduce the number of CodeSniffer
violations.
