Add more gettext markers.

Fix typo-like error for the interpretation of the `[timeline] changeset_long_messages` configuration setting.

Partially revert r6227 (trac/core.py), as this triggered an internal error with mod_python.

The `from trac.util.translation import _` in trac/core.py was triggering a recursive import of `trac.core.TracError` via `trac/util/__init__.py`:
{{{
...
[error] File "/packages/trac/branches/upstream-trunk/trac/core.py",
line 19, in ?\n from trac.util.translation import _
[error] File "/packages/trac/branches/upstream-trunk/trac/util/__init__.py", line 31, in ?\n from trac.core import TracError
[error] ImportError: cannot import name TracError
}}}

Convert more TracErrors to the common style.
Add gettext markers.

Add more gettext markers.

On project creation, it is now possible to pass in an option for the `[inherit] file =` setting, and have the environment be a bit smarter on creation.

It will now load inherited settings when created, and not write defaults to project trac.ini except what is entered through the `initenv` console session or passed in as options to `Environment.create()`.

Command line option looks like this (can be appended to both variations of `initenv`):
{{{
trac-admin /path/to/new/env initenv --inherit=/path/to/global/trac.ini
}}}

Also includes a fix for not writing `[ticket-workflow]` when that section exists in the inherited trac.ini.

Closes #5651.

Setting height and width for header logo should now work with 0.11.
Values of 0 or -1 means the attributes will not be set.

Fixes #4696.
