Subject: Remove $wgUseTeX for checking if editing tools should be shown
X-Git-Tag: 1.31.0-rc.0~17099^2
X-Git-Url: http://git.cyclocoop.org/wiki/Target_page?a=commitdiff_plain;h=f4ecc574f0d2b65aafde269780e2a4cdc1642424;p=lhc%2Fweb%2Fwiklou.git

Remove $wgUseTeX for checking if editing tools should be shown

The EditPage toolbar used the global $wgUseTeX to determine, if
the icon for inserting math should be shown. Now we simply check
if the class MathRenderer exits.
