It is easy to make bugs and (IMHO)
it is not so useful in these days.

See:
Yona Github issues #122 #93

Also, this commit fixes css layout for ipad mini retina.

See: Yona github issue #120

See: Yona Github issue #123

See: github issue #124

in My File menu.

Now, user can see their own attachment files.

Caveat:
Mobile view isn't refined yet.

To increase performance and use more options,
upgrade MariaDB connector to v1.5.5

You can see available options and discussions:

Instead of YONA_HOME, use YONA_DATA.

If you set a YONA_DATA and run bin/yona,
conf, uploads, repos, logs will be stored at YONA_DATA folder.

eg.
YONA_DATA=/yona-data;export YONA_DATA
bin/yona

It will make easy to upgrade and backup
YONA_HOME is no longer needed.

and support creation date tooltip

- Increase title of issue/post list font size: 15px -> 16px
- Change default label color sets
- Modify project label buttons margin at low resolution

Some file names can be non url allowed strings which called unsafe chars.
In that case, Yona code browser couldn't parse properly.

This commit fix it.
