Bug 11810: Input fields in OPAC suggestion form are a bit short (Bootstrap)

The default Bootstrap input size (absent any specific input size or
class) is too short for the suggestion form. This patch adds a Bootstrap
class to fields which need more room and adjusts the OPAC CSS to allow
for better handling of input width at lower screen widths.

To test apply the patch and clear your browser cache if necessary. Open
the "new suggestion" form in the OPAC and confirm that the entry fields
for title, author, publisher, and collection title are sized well.

Adjust the width of your browser window up and down to confirm that the
field sizes adjust well at various screen widths.

Followed test plan. Works as expected.
