#248 php substitution

[ssd]

Using stock php in CentOS 6, some php variable substitutions fail due to inconsistent dated php syntax in seed dms code. This patch fixes a few instances found in seeddms/views/bootstrap/class.Bootstrap.php by making the substitution syntax consistent with other similar syntax that works.

Possibly there are more of these in other files. This particular set prevents the tree in the left pane from being expanded.

This must be a php version < 5.4. Since php 5.4 the syntax <?= is available even if short_open_tags or off. If you turn on short_open_tags it should work with < 5.4 as well.

The remaining short tags has been replaced.
