Toggle Word Wrap for Thunderbird 1.3

Toggle Word Wrap for Thunderbird 1.3 is a firefox extension. With Thunderbird, it comes in handy when inserting long text lines which should not get wrapped in the final message (such as log file entries, or diffs inserted into the message body).

It only has an effect when using plain text mode for composition - this is a per-account setting which must be configured by disabling "Composition & Addressing" -> "Composition" -> "Compose messages in HTML format".

Major Features:

1. Unchecking "Enable Word Wrap" in the Options menu (or pressing the keyboard shortcut) will temporarily turn off word wrapping for the current message - lines will take up the whole width of the composer window, and no line breaks will get added to the outgoing message (with the exception of "hard" line breaks inserted manually).
2. Checking "Enable Word Wrap" will enable word wrapping again and set it to the width specified in the standard settings ("Wrap plain text messages at", default is 72 characters).
3. For Firefox, checking "Word Wrap Within PRE" in the View menu will temporarily enable word wrapping for PRE tags in the current document (by adding a CSS rule to the HEAD element). Unchecking the menu entry will revert the document to the previous state (no word wrapping). The following page can be used to see the effect, e.g.: http://users.tkk.fi/~tkarvine/pre-static-no-css.html
4. Releases 1.0 and later are provided as a signed XPI file. The signature will successfully verify if the "Builtin Roots Module" is enabled in its standard configuration. Errors like "could not install the file ... because: Signing could not be verified" indicate that either the XPI file has been tampered with or the trust settings of the built-in certification authorities have been tweaked. (In the latter case, I assume that you're also savvy enough to figure out what trust anchor needs to be re-enabled in order to make the verification succeed again... or how to rip the signature out of the file, otherwise ;-)
