Broken "Enable Profiling" button if button value contains special characters

This bug can potentially break the profiling activation in Confluence.

Steps to reproduce:

1. Install and activate a foreign language pack. Japanese and Chinese are good examples.
2. Activate profiling (admin/viewlog4j.action) by clicking on the "Enable Profiling" button. Activation fails.

<input type="submit" name="profilingButtonValue" value="プロファイル作成を有効にする">

This one always returns false:

    public void setProfilingButtonValue(String buttonValue)
    {
        profilingOn = getText("loglevel.profilingOn").equals(buttonValue);
    }

As a workaround, edit the button value as defined inside the plugin's properties file. For instance, in the Japanese language pack:

loglevel.profilingOn=\u30d7\u30ed\u30d5\u30a1\u30a4\u30eb\u4f5c\u6210\u3092\u6709\u52b9\u306b\u3059\u308b

Edit the value to only consist English characters such as:

loglevel.profilingOn=Enable Profiling

(This will, of course, display the button value in English rather than Japanese).
