Broken egg install, conflict with tracusermanagerplugin 0.3

[Michał Małecki]

After standard egg installation, JS and CSS files are not present. While building an egg with setup bdist_egg, html calatogue is not included within the egg - thus plugin does not work. The appropriate directory in .egg-cache dir in trac env does not get created.

After copying html directory manually to Lib/site-packages/trac/ in python installation, it appears to work, but just till the restart of the httpd server.

After restart it starts to conflict with requests to graphics and CSS from tracusermanagerplugin , every http request resulting in http 500 message with following error:

  Trac detected an internal error:
  KeyError: 'autocompleteusers\\htdocs'

and following traceback:

We suspect that the problem is in line no.4 in a traceback - the refference to a nonexistent dirctory from build directory of an egg distribution.

r4390 should at least include the js and css (i hope)

This can be fixed with the following patch:

(In [5047]) more explicit specification of package_data; bump version; add GPL license; hopefully fixes #3758
