Increase max boulder title length

[juangallostra]

Boulder title length is set to 26 characters, which might be a bit short:

RocoLib/templates/save_boulder.html

Line 32 in bb65390

<input id="name-field" type="text" name="name" value="" maxlength="26" required /><br /><br />

As an example, names such as Regala regletas y no galletas are not possible to set. Change it to something larger, i.e 60?
