Uses deprecated SHA-1 hash API

[anonymous]

The plugin seems to work with recent versions of Trac/Python, but generates deprecation warnings. It looks like the fix is pretty simple:

$ diff tracmath.py tracmath.py.orig
8c8
< import hashlib
---
> import sha
145,147c145
<         sha1hasher = hashlib.sha1()
<         sha1hasher.update(content.encode('utf-8'))
<         key = sha1hasher.hexdigest()
---
>         key = sha.new(content.encode('utf-8')).hexdigest()

This was already fixed in the 0.3 release. Please download a more recent version of the plugin.
