Merge pull request #3 from kobliha/master

Thanks! Merging to master...
models/online_help.rb is not needed anymore
initial support for token authentication
updated login checks
updated schema to match the migrations
periodically remove expired auth tokens

via delayed job
sessions - added XML output support
decreased logging
skip cleanup when "accounts" tab doe not exist yet

(this file also used in rake tasks)
update DB schema in plugins
added global "rake osc_submit" to submit all plugins to OBS
html_helper.rb - removed excessive </p> tag from report_error() helper
run some tasks in parallel

(use rake multitask feature)
status - fixed test, added nil check
Merge branch 'master' into token_auth
- macros.webyast - use Gemfile.test earlier

(when creating test DB)
the created Gemfile.test.lock fixes segfault during build on IA64

(yes, a strange solution for the crash...)

- 0.3.4
base - fixed PluginJob restart (bnc#779239)
base - 0.3.20
macros.webyast - this is actually the needed fix for IA64...
- fixed PluginJob detection (bnc#779239)

- 0.3.21

move the find code to PluginJob.find
