Error displaying timeline with space in job_url or main_url

[franck villaume]

My hudson job name contains space.

If I provide the job_url with space, when I click on timeline I have this error : Hudson Builds event provider (HudsonTracPlugin) failed: UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 40: ordinal not in range(128)

And If I provide the job_url using the %20 code for space, when I click on timeline I have this error : Hudson Builds event provider (HudsonTracPlugin) failed: ValueError: unsupported format character 'I' (0x49) at index 49

(In [7277]) Fix two issues with special characters in job url:

1. properly handle '%' in url
2. escape non-safe characters in url (such as spaces, non-ascii characters, etc)

This fixes #6349.
