Update initial_request.text.erb

Use the raw helper so that characters like ' are not HTML escaped in outgoing email messages.  This is already done in the initial_request.text.erb shipped with Alaveteli.

Only set up FastGettext on initialization, even in development mode

Even on a very fast computer, there is a significant delay (a couple
of seconds) in processing every request in development mode.  This
is because the configuration of FastGettext's paths for finding
translations is done in a block passed to
Rails.configuration.to_prepare, which causes the block to be run
before every request by the Rails Reloader in developmetn mode.

It seems to be work fine just running the FastGettext calls on
initialization in development mode, however - customizations in
the theme's locale-theme directory still have effect in
development mode even after the reloader has reloaded classes
before handling subsequent requests.  So, I think this change
should be safe.  This commit introduces that change, having the
effect that development mode is much more responsive.

Switch to work with the feature/wip-switch-to-asset-pipeline branch
Refer to the precompiled application.css, which includes custom.css
Move images out of /public and into the asset pipeline

An oddity here is that I had to rename logo.png to
alaveteli-logo.png, or the version from the alaveteli
repository was used after precompiling the assets.
(This suggests that generation of precompiled assets
with "rake assets:precompile" is picking the wrong
version; i.e. not going through the asset path in
reverse order.)
Revert renaming of the logo.png file
Merge branch 'switch-to-asset-pipeline' into develop
No need to create or destroy symlinks now

Handled by asset pipeline.
Add .css suffix before .scss for consistency.

Doesn't seem to make any difference to preprocessing behaviour.
Restore logo.png
