Update trac 1.4.4

[bmispelon]

Most of the work is from Florian's original PR: #133

In addition, I made the following changes:

• removed warnings about missing js files (Florian deleted them but left the <script> tags in the html)
• bumped version for Trac (1.4.4 instead of 1.4.3 and a slightly more recent version of the xmlrpc plugin)
• fixed a styling issue with bold text in the navigation
• updated the box-shadow scss reset, and created the noshadows.py script to automate that task. The script has some builtin tests when called with --tests, not sure if it's worth adding those to CI too.

Trac being trac, my local testing on a blank instance was limited but I think this PR is good enough to be merged. I'd like to continue the upgrade work once this is merged so we can finally move off Python 2 and Django 1.11 🧓🏻 .

Here are a few random tips that helped me test things locally:

• turn on more verbose logging in trac.ini (I used log_level = INFO and log_type = stderr)
• comment out the [notification] and [notification-subscriber] sections in trac.ini to avoid errors while sending emails after ticket creation/update

I applied black, please rebase.

PR rebased and ready to test (I also noticed and fixed a styling issue where the ticket box had lost its themed background color)

EDIT Fixed now ✅

Just noticed something is wrong with the noshadows.py script, it's not handling handling some selectors correctly and some bax-shadows are visible as a result (#mainnav for example). Working on it 🔨

Issue #141 will also be fixed by merging this

[felixxm]

I merged 4221609 because it's compatible with Trac 1.2.6.

@bmispelon I'm looking at 39e46f7. Do you think we can remove these files in advance? i.e. is it compatible with 1.2.6?

I'm not sure it's safe to delete all of them (looking at mobile-menu.js for example, it seems it's used to generate the navigation menu for the mobile version). I'm going to try and investigate which files are currently unused (or safe to delete) so we could minimize the diff. I'll keep you posted.

EDIT: Turns out that the deletion were maybe a bit hasty since some js was still used for the mobile version of the navitation, as well as loading some fonts that were used. See PR in next comment

Here's a PR that removes the js files that were not used: #149

Once that one is merged, I'll rebase this one and resolve the conflicts that arise.

@felixxm I've rebased this branch after the merging of #149 . I've taken the liberty to squash some commits together when I thought it made sense, I hope that's ok (if not let me know and I'll try to undo my git mess 😅 ). Hopefully that makes the reviewing easier.

Let's try, merged 💥
